Participants

Reaction Steps

To 100 ml of an ethanol solution containing 17.0 g of methyl 3-bromo-2-methyl-6-methylthiobenzoate, 16 g of a 50% sodium hydroxide aqueous solution was added, and the mixture was refluxed for 3 hours under heating. The reaction mixture was concentrated under reduced pressure. Then, water was added thereto, and the mixture was washed with chloroform. The aqueous layer was acidified with concentrated hydrochloric acid and extracted with chloroform. The extract was dried over anhydrous sodium sulfate. The solvent was distilled off to obtain 15.9 g of the desired product. Melting point: 98°-103° C.
