HCID 13734319Cyclohexanecarbonyl chloride, 5-methyl-2-(1-methylethyl)-

Procedure

Menthane-3-carboxylic acid (54.35 g) was refluxed with 80 ml of thionyl chloride for 3 hours. The SOCl2 was removed by distillation, and the acid chloride was distilled at 114-115° C. (8 Torr). (Lit. b.p. 84-85° C. at 3.5 Torr). Yield: 50 g (84%).

Workup
