실험 절차
The product from Example 1 (10.5 g) was refluxed for 2.5 hours in ethanol (200 ml) containing sodium borohydride (6 g). The reaction was cooled to room temperature and evaporated to dryness. Aqueous hydrochloric acid (50 ml) was carefully added followed by extraction with dichloromethane. The organic layer was separated, dried and evaporated affording 8.4 g. of the desired product (79% yield); m.p. 50°-1° C.
