Reaction Steps

A solution of 4-{5-[4-hydroxymethyl-4-(3-trifluoromethoxy-benzyl)-piperidine-1-ylmethyl]-2-methylimidazol-1-ylmethyl}benzonitrile (71 mg, 0.142 mmol; Example 31) and sodium perborate tetrahydrate (92.8 mg, 0.6 mmol) in a mixture of methanol (2.5 mL) and water (1 mL) was heated at 50° C. for 7 h. The resultant mixture was concentrated under vacuum, and the residue was partitioned between chloroform and dilute hydrochloric acid (0.5 M). The organic extract was washed with brine, dried over anhydrous sodium sulfate, filtered, and concentrated under vacuum. The residue was subjected to column chromatography on silica gel eluting with 10% methanol in chloroform. Collection and concentration of appropriate fractions provided the title compound as white solid.
