Procedure

A solution of 1-[3-(4-cyanobenzyl)-3H-imidazol-4-ylmethyl]-4-(3-methylbenzoyl)piperidine (175 mg, 0.44 mmol; Example 104) in methanol (5 mL) was treated with sodium borohydride (12 mg, 0.31 mmol) at room temp. The resultant solution was stirred at room temp. for 30 min., and concentrated under vacuum. The residue was subjected to column chromatography on silica gel eluting with chloroform saturated with ammonia gas. Collection and concentration of appropriate fractions provided the title product.
