実験手順

The procedure of Reference Example 1 was repeated except that 35.4 parts of ethyl 3,3-dimethyl-4-bromo-6,6,6-trichlorohexanoate was used in lieu of ethyl 3,3-dimethyl-4,6,6,6-tetrachlorohexanoate. By this procedure was obtained 19.0 parts of 3,3-dimethyl-4-(2',2'-dichlorovinyl)-4-butanolide (yield 90%).
