실험 절차

A mixture of 10.0 g. of p-chloroacetophenone and 25 ml. of dimethylformamide dimethylacetal is refluxed for 3 hours. Evaporation gives a thick oil which crystallized with the addition of hexane, to give the product, m.p. 78.5°-80.5° C. Recrystallization from methylene chloride and hexane provides the product of the Example as crystals, m.p. 83°-84° C.
