At the end of this time, the reaction mixture was washed with water and dried over anhydrous sodium sulfate. The toluene was removed by distillation under reduced pressure, and the oily product thus obtained was subjected to column chromatography (Wakogel C-200, eluted with a 2:1 by volume mixture of toluene and ethyl acetate) to isolate the product. The crystals thus obtained were recrystallized from hexane to afford 2.6 g of the title compound as colorless needles melting at 57°-58° C.
