Participants

Reaction Steps

1.2 g of sodium borohydride are added in portions to a solution of 7.7 g of the product obtained in Step A in 100 ml of ethanol. After 1 hour's reaction, the solution is evaporated, taken up in water, extracted with ethyl acetate, dried and then concentrated under reduced pressure. Chromatography over silica gel (dichloromethane/ethanol: 95/5) enables the expected product to be isolated.
