Reaction Steps

A solution of 40 ml (0.5 mol) of sulphuryl chloride in 100 ml of chloroform is added dropwise to a solution of 26.1 g (0.1 mol) of 3-bromo-2,6-dimethoxybenzoic acid in 150 ml of chloroform. After a night at room temperature the solution is refluxed for 45 minutes. The solvent is evaporated and the residue recrystallized from isopropyl ether - light petroleum. Yield: 23.5 g, m.p. 98.5°-100° C.
