To prepare 5- [1 - (2,3 - dimethylbenzyl) ethyl] -1H - indole - 2 - carboxylic anhydride (1:1), there are many methods for its synthesis, which are described in detail below.
First, react with 2,3 - dimethylbenzyl halide and vinyl Grignard reagent to obtain 1- (2,3 - dimethylbenzyl) ethylene first, then oxidize with borohydride, halogenate, and then couple with indole - 2 - carboxylic anhydride under the action of base to obtain the target product. This approach is more complicated, but the reaction conditions of each step are relatively mild and easy to control.
Second, the condensation of 2,3-dimethylbenzaldehyde with diethyl malonate to obtain α, β-unsaturated esters, and the reaction with indole-2-carboxylic anhydride after reduction and halogenation can also achieve this purpose. The raw materials of this method are easy to obtain, and the cost may be reduced. However, the condensation reaction needs to be precisely regulated to avoid the growth of side reactions.
Third, the precursor containing 2,3-dimethylbenzyl and indole-2-carboxylic anhydride parts is synthesized first, and then the target structure is constructed by intracyclization reaction. Although this strategy is short, the cyclization reaction requires strict requirements on the structure and conditions of the reaction substrate, and needs to be carefully optimized.
Fourth, cross-coupling reactions catalyzed by transition metals, such as palladium-catalyzed reactions. Using suitable halogenated aromatics, alkenyl halides and indole-2-carboxylic anhydride derivatives as raw materials, in the presence of palladium catalysts and ligands, the product is synthesized by coupling reaction. This method has high efficiency and good selectivity, but the catalyst cost is high, and the reaction equipment and operation requirements are also strict.
All the above synthesis methods have advantages and disadvantages. The actual preparation requires careful selection based on factors such as the availability of raw materials, cost considerations, difficulty in reaction operation, and purity requirements of the target product.

From what you have said, it seems to involve a rather uncommon thing, namely "5- [1- (2,3-dimethylbenzyl) ethyl] -1H-pyrazole-3-formic anhydride (1:1) ". However, it is difficult to determine the price range of this product in the market.
The fluctuation of prices in the market is affected by many factors. First, the price of raw materials is constantly changing. If the supply of 2,3-dimethylbenzyl and other raw materials required for the production of this product is different, the price will fluctuate accordingly. If the supply is sufficient, the price will be stable and low, and if the supply is insufficient, the price will rise. Second, the difficulty of preparation is related to cost. If the preparation process of this anhydride is complicated and requires high-end equipment, a lot of manpower and special reagents, the cost will be high and the price will be high; if the process is relatively simple, the cost will be controllable, and the price will be close to the people. Third, the amount of market demand is also the key. If this anhydride is in high demand in chemical, pharmaceutical and other fields, the supply is in short supply, and the price will rise; if the demand is low, the supply will exceed the demand, and the price will fall.
And this product or a relatively niche chemical product, the price is also different in different regions and different suppliers. Or in prosperous cities, due to convenient logistics and fierce competition, the price may be slightly lower; in remote places, due to transportation costs, the price may be slightly higher.
To sum up, it is difficult to say exactly what the price range of "5- [1- (2,3-dimethylbenzyl) ethyl] -1H-pyrazole-3-formic anhydride (1:1) " is in the market without detailed investigation of multi-party market information, raw material costs, preparation processes, and market supply and demand.
