Procedure

To a stirred solution of 3.8 g (10 mmoles) of the compound of Example 9 in 50 ml ethanol chilled to 0°-5°, was added 1.0 g (25 mmoles) sodium borohydride all at once. After 0.5 hour at that temperature, the cooling was discontinued, and the reaction was allowed to proceed at room temperature for 1 hour. The reaction mixture was then chilled to 0°-10° C., and 40 ml of 2 N HCl was cautiously added, followed by another 40 ml of water. Most of the ethanol was removed under vacuo. The crystalline product was collected by filtration, washed with water, and air dried. Recrystallization from acetonitrile yielded 3.9 of the title compound, m.p. 242°-245°. The infrared and NMR spectra were consistent with the assigned structure.
