In the early steps, the reaction conditions and reagents are carefully selected to ensure the selectivity and yield of the reaction.
When constructing the 4-bromobenzyl moiety, it can start from a suitable aromatic hydrocarbon, introduce bromine atoms through bromination reaction, and then access the benzyl structure through alkylation reaction. For the modification of the 2-moiety, the appropriate reaction path needs to be selected according to the overall molecular design. The formation of the
1H-indole structure is often a key step. It can be formed by the cyclization reaction of o-amino benzaldehyde or its derivatives with carbonyl-containing compounds. The control of this cyclization reaction conditions is very important, such as temperature, catalyst type and dosage, which will affect the reaction process and product purity. In the reaction, the catalyst can be selected from Lewis acid or proton acid, etc., and the choice is optimized according to the characteristics of the substrate.
During the synthesis process, the reaction process needs to be closely monitored. The reaction is often tracked by thin-layer chromatography (TLC). When the reaction reaches the expected level, post-treatment is carried out in a timely manner. Post-treatment includes extraction, washing, drying, column chromatography separation and other steps to obtain a pure product.
The synthesis process should also pay attention to safety and environmental protection. When selecting reagents and reaction conditions, try to avoid highly toxic and highly polluted materials, and optimize the reaction process to reduce waste generation, making the synthesis path greener and more sustainable. In this way, through multiple steps of exquisite design and operation, the target product 2 - (4-bromobenzyl) -1H-indole can be obtained.

I think what you are asking is about the market price of 2- (4-cyano) -1H-indole. However, the price of this product often changes for many reasons, and it is difficult to determine its fixed number.
The market price is mainly related to supply and demand. If there are many people who want it, but there are few suppliers, the price will increase; on the contrary, if the supply exceeds the demand, the price will drop. And the difficulty and cost of its preparation are also the key. If the preparation is complicated, the required raw materials are expensive, and the process is strict, the cost will be high, and the market price will also be high.
Furthermore, the price varies from place to place and at different times. In the bustling city, due to the concentration of demand and active business, the price may be different; in remote places, or due to logistics inconvenience, the price may also be different. The change of time, the innovation of technology, and the rise and fall of raw materials can all cause the price to change.
If you want to know the exact market price, you should carefully observe the dynamics of the chemical market, consult industry experts, or visit the chemical trading platform, so that you can get a more accurate price. However, it is difficult for me to give you a definite number at this time. I hope you can find the required price according to this route.
