Procedure

1 mmol of the compound obtained in Step A is dissolved in 15 ml of ethanol, and 1.5 mmol of NaBH4 are added in two portions. The reaction mixture is stirred for 3 hours; the reaction is then quenched using 0.5 ml of acetic acid; the mixture is rendered basic with 10% NaOH, and extracted with dichloromethane (3×15 ml). The organic phase is dried over MgSO4, evaporated and the solid obtained is recrystallised from ethanol.
