실험 절차
To a 30 ml of dichloromethane of 1.5 g of 2-(4,4'-difluorobenzhydrylidene)-1,3,5-trithiane was added 0.77 g of m-chloroperbenzoic acid in small portions at 0° C., and the resulting mixture was stirred overnight. After completion of the reaction, the reaction mixture was poured into ice-water and extracted with dichloromethane. Usual work up gave crude solid, which was purified by a silica gel column chromatography (chloroform:hexane=3:1) to obtain 1.2 g of white crystals.
