Procedure
A solution of 4-(3-methylbenzyl)isonipecotamide hydrochloride salt (134 mg, 0.5 mmol), 1-(4-cyanobenzyl)-5-chloromethyl-imidazole hydrochloride salt (134 mg, 0.5 mmol; Example 52, Step D), and diisopropylethylamine (440 mL, 2.5 mmol) in anhydrous acetonitrile (5 mL) was heated under reflux overnight. The resultant mixture was concentrated under vacuum. The residue was subjected to column chromatography on silica gel eluting with 2% methanol in chloroform saturated with ammonia gas. After collection and concentration of appropriate fractions, the residue was triturated with anhydrous diethyl ether. The white solid precipitated was filtered to provide the title compound.
