Reaction Steps
Using the procedure of Step B of Example 1, 951 mg of benzimidazole and 1.97 g of 4-bromomethyl benzonitrile in dimethylformamide were reacted to obtain 2.48 g of crude product which was chromatographed on silica (eluant:methylene chloride-methanol (95-5)) to obtain 1.34 g of the desired product melting at 94° C. after crystallization from ether. An analytical sample was prepared by two successive crystallizations of 422 mg of the product from ether, then from isopropyl ether to obtain 167 mg of pure product melting at 94° C.
