Procedure

1-Bromocyclohexyl (2,3-dichloro-4-methoxyphenyl) ketone (47.3 g., 0.13 mole), lithium chloride (16.5 g., 0.39 mole) and dimethylformamide (200 ml.) are heated at 90°C. for two hours, then poured into water (1 l.) to give 36.5 g. of 1-cyclohexenyl (2,3-dichloro-4 -methoxyphenyl) ketone which melts at 126°-129°C. after drying at 60°C. under vacuum for 16 hours.
