Reaction Conditions

Reaction Steps

A solution of Example 189 compound (400 mg, 1.13 mmol) in 25 ml of methanol was cooled to 0° C. under an argon atmosphere. Sodium borohydride (93 mg, 2.45 mmol) was added portion wise over 10 minutes and the mixture was then stirred for 30 min. longer at 0° C. The reaction was diluted with 0.1 N hydrochloric acid to pH 4. The reaction mixture was diluted with 30 ml of water and extracted with ethyl acetate (3×20 ml). The ethyl acetate extract was washed with water, brine and dried over sodium sulfate. The crude product was purified on a Merck EM silica column eluting with 10% ethyl acetate/hexane yielding 345 mg (86%) of title compound as a colorless oil.
