What is the function of 2-Chloro-1-(4-Methylphenyl)-1-Propanone Cas 69673-92-3 ?
The invention relates to a method for preparing a key intermediate of closolprofen, 2-p-chloromethyl phenylpropionic acid. The method starts with toluene as raw material, through condensation with propionyl chloride to get p-methyl phenylacetone, and then through one-step bromination, carbonyl methoxylation, hydrolysis to get 2-p-methyl phenylpropionic acid, and finally chlorine generation to get 2-p-chloromethyl phenylpropionic acid.
