Thionyl chloride (51.2 g, 0.43 mol) was added to optically active p-(1-methyl-heptyloxy)benzoic acid (90.0 g, 0.36 mol), followed by refluxing the mixture for about 2 hours, thereafter completely removing excess thionyl chloride by distillation under reduced pressure to obtain optically active p-(1-methyl-heptyloxy)benzoic acid chloride (90.0 g).
