실험 절차

A mixture of 2,4-bis(trichloromethyl)benzo[1,3]dioxin-6-carbonyl chloride (2 g.) and diethylamine (25 ml.) was heated under reflux for 2 hrs., cooled, and filtered to remove diethylamine hydrochloride. The filtrate was evaporated to dryness under reduced pressure, and the residue was crystallised from ethanol to give 4-dichloromethylene-N,N-diethyl-2-trichloromethylbenzo[1,3]dioxin-6-carboxamide, m.p. 123°-124° C.
