Reaktionsschritte
A solution of 11.5 g. (0.07 mol.) of 3-methyl-4-methoxybenzoic acid and 10.7 g. (0.09 mol.) of thionyl chloride in 60 ml. of methylene chloride is refluxed on a steam bath for two hours. Concentration under reduced pressure and distillation of the residue gives 3-methyl-4-methoxybenzoic acid chloride, m.p. 37°-39°.
