反応手順
A solution of 16.2 ml (0.2 mol) of sulphuryl chloride in 100 ml of chloroform is added dropwise while stirring to a solution of 36.4 g (0.2 mol) of 2,6-dimethoxybenzoic acid in 300 ml of chloroform. The mixture is heated for 0.5 h at 50° C. and left overnight at room temperature. The solvent is evaporated and the residue recrystallized from isopropyl ether--light petroleum. Yield: 35.4 g, m.p. 132°-33° C.
