実験手順

At RT, 0.5 ml (3.8 mmol, 1.2 eq.) of diethylaminosulphur trifluoride was added dropwise to a solution of 1.55 mg (3.13 mmol) of tert-butyl 2-[4-(5-chloro-2-cyanophenyl)-5-methoxy-2-oxopyridin-1(2H)-yl]-3-hydroxy-3-(tetrahydrofuran-3-yl)propanoate (diastereomer mixture) in 48 ml of dichloromethane, the mixture was stirred at RT for 90 min and 50 ml of dichloromethane and 50 ml of saturated aqueous sodium bicarbonate solution were then added. After phase separation, the aqueous phase was extracted with dichloromethane. The combined organic phases were washed with saturated aqueous sodium chloride solution, dried (sodium sulphate), filtered, concentrated under reduced pressure and dried. Yield: 1.38 g (93% of theory)
