Reaction Steps

A solution of 15 ml of bromine (0.3 mol) in 50 ml of chloroform is added dropwise while stirring and cooling in ice to 54.9 g (0.3 mol) of 2,6-dimethoxybenzoic acid in 150 ml of dioxan. The solution is left at room temperature overnight. The solvent is evaporated and the residue recrystallized from aqueous ethanol. Yield: 59.3 g, m.p. 144°-45° C.
