실험 절차

3,4-Dimethyl-2-pentenoic acid (XI, 4.1 g) was heated to a gentle boil with thionyl chloride (50 g) in benzene (50 mL) until the generation of hydrochloric acid gas ceased. Removal of the excess thionyl chloride and benzene by evaporation in vacuo followed by a distillation of the reaction product gave pure 3,4-dimethyl-2-pentenoylchloride (IX, 64° C. (9.5 mm)).
