実験手順

A solution of 4-cyano-4-[3-cyclopentyloxy-4-(4-fluorobenzyloxy)phenyl)cyclohexan-1-one (0.525 g, 1.49 mmol) and hydroxylamine hydrochloride (0.114 g, 1.63 mmol) in pyridine (5 mL) was was stirred at room temperature under an argon atmosphere for 18 h. The mixture was partitioned between 1N hydrochloric acid and methylene chloride, the organic extract was dried (magnesium sulfate) and the solvent was removed in vacuo. Purification by flash chromatography, eluting with 35% ethyl acetate/hexanes, provided a white solid (0.45 g, 82%): m.p. 55°-57° C.
