Procedure
70 g (0.38 mol) of methyl 3-thio-2-methylbenzoate are dissolved in 400 ml of water and refluxed for 7 hours together with 30.8 g (0.77 mol) of sodium hydroxide solution and 58.8 g (0.45 mol) of bromopropionic acid. After cooling, the aqueous phase is washed using methyl tert-butyl ether. The aqueous phase is subsequently acidified using 2N HCl, the precipitate which has formed is filtered off with suction and washed with water, and the product is dried.
