실험 절차

A stirred mixture of 1-(4-methoxyphenyl)-2-propanone (8.2 g) and dimethylformamide diethyl acetal (9.5 ml) was heated on an oil bath at 95°-100° C. for 30 minutes. Volatile material was removed under vacuum and the residue was crystallised from ether-petroleum spirit (40°-60° C.) to give the title compound (mp 56°-58° C.).
