To prepare 2 - (5 - hydroxy- 2 - methylbenzylformamido) - 5 - (4 - fluorobenzyl) pyrimidine, you can follow the following ancient method.
First take an appropriate amount of 5 - hydroxy- 2 - methylbenzylformamide, place it in a clean reactor, dissolve it in a suitable organic solvent, such as dichloromethane or N, N - dimethylformamide, to make a uniform solution. In this solution, slowly add an appropriate amount of alkali, such as potassium carbonate or sodium carbonate, to adjust the pH of the reaction system and create a suitable reaction environment. The amount of alkali needs to be accurately measured according to stoichiometry to ensure a smooth reaction.
At the same time, another container is prepared, and the 4-fluorobenzyl halide containing the halogen, such as 4-fluorobenzyl chloride or 4-fluorobenzyl bromide, is also dissolved in an organic solvent. After the previous reaction system is stabilized, the solution containing the halogen is added dropwise into the reactor, and the dripping speed should be slow to prevent the reaction from being too violent. After adding dropwise, maintain the reaction system at an appropriate temperature, or at room temperature, or heated to a certain temperature, and adjust it according to the reaction process. During the reaction, it is advisable to stir it so that the reactants are fully contacted to promote the rapid progress of the reaction.
During the reaction process, a small amount of samples should be taken at regular intervals, and the reaction process should be monitored by thin layer chromatography or other suitable analytical methods until the raw materials are almost exhausted and the amount of product generated reaches the expected value. After the reaction is completed, the reaction solution is poured into an appropriate amount of water, and the product is extracted with an organic solvent. The extraction solution is dried with anhydrous sodium sulfate or magnesium sulfate to remove the water. Then, the organic solvent is removed by distillation under reduced pressure to obtain a crude product.
The crude product needs to be further purified. Column chromatography can be used to separate and purify silica gel as the fixed phase and a suitable proportion of petroleum ether and ethyl acetate mixture as the mobile phase. The fractions containing the target product were collected and distilled again under reduced pressure to remove the mobile phase to obtain a pure 2- (5-hydroxy- 2-methylbenzylformamido) -5- (4-fluorobenzyl) pyrimidine product. The whole process requires strict compliance with operating procedures and attention to safety to obtain qualified products.
