Procedure

To a solution of the compound prepared in Example 23 (135 mg) in tetrahydrofuran (1.2 ml)-ethanol (0.3 ml) were added portionwise nickel chloride hexahydrate (70 mg) and sodium borohydride (45 mg) at 0° C. The mixture was stirred for 15 minutes. The reaction mixture was extracted with diethyl ether. The organic layer was filtered. The filtrate was extracted with diethyl ether. The organic layer was washed with a saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate and concentrated to give the title compound having the following physical data.
