実験手順

To a mixture of 4-chlorobenzalpinacolone (22.3 g), triethylamine (5 drops) and ethanol (250 ml) was added thiophenol (12 g) and the mixture was kept to 70° C. for 4 hours. After ice-cooling, the resulted precipitates were collected by filtration, washed with cold ethanol and dried to give white crystals of the captioned compound (29 g; 84%). m.p. 127°-128° C.
