실험 절차

A solution of 63.9 g of 3-acetoxy-7α-(5-acetoxypentyl)-estra-1,3,5(10)-trien-17-one in 460 ml of dichloromethane is stirred with 460 ml of ethylene glycol, 155 ml of trimethyl orthoformate and 1.2 g of para-toluenesulfonic acid for 3 hours at a bath temperature of 50° C. Then, it is diluted with dichloromethane, washed with sodium bicarbonate and common salt solution and dried on sodium sulfate, concentrated by evaporation in a vacuum and chromatographed on silica gel with hexane/ethyl acetate. 63.2 g of 3-acetoxy-7α-(5-acetoxypentyl)- 17,17-ethylenedioxy-estra- 1,3,5(10)-triene is obtained as oil.
