실험 절차

The product from step (a) (0.17 g) was dissolved in ethanol (3 ml) and a solution of 4,4-diphenylpiperidine (0.118 g) in ethanol (1 ml) added. A solution of sodium cyanoborohydride (1.0 M in tetrahydrofuran, 3.0 ml) was added and the solution stirred at room temperature for 16 hours. Silica gel was added, the solvent removed by evaporation and the crude material purified by chromatography (dichloromethane:methanol, 100:0 to 95:5) to give the product as an oil. Further purification by supercritical fluid chromatography gave the product as a solid (0.010 g), m.p. 167-168° C.
