Reaction Steps

A mixture of N-(4-Aminobenzyl)-4-methoxybenzamide (15 g, 58.4 mmol), 2-chloroimidazoline sulfate (15.2 g, 74 mmol) and 2-propanol (380 mL) was heated at reflux for 2.5 h under N2. The mixture was cooled to 0° C. and filtered, and the filtrate was concentrated to dryness. To the resulting residue 10% aqueous sodium hydroxide was added to reach pH 13–14. The resulting suspension was filtered, and the solid N-[4-(4,5-dihydro-1H-imidazol-2-ylamino)-benzyl]-4-methoxybenzamide was crystallized from dichloromethane. Weight 11.9 g (61.4% yield). mp 160.3–160.6° C.
