Procedure
The product of Example 324C (0.167 g, 0.30 mmol) in tetrahydrofuran (6 mL) and methanol (0.030 mL, 0.8 mmol) at 0° C. was reacted with lithium borohydride (2.0 M solution in tetrahydrofuran, 0.250 mL, 0.50 mmol). The reaction was stirred at 25° C. for 1.5 hour, acidified to pH 2 with 1 M aqueous hydrochloric acid and diluted with water (25 mL). The resulting precipitate was collected by filtration and dried to constant weight to give the title compound (0.114 g, 69%).
