A 19.42 g. portion of 2-(2-pyridyl)-2-phenylacetonitrile was stirred with 4.8 g. of 50% sodium hydride in 50 ml. of dimethylformamide, and reacted with 7.65 g. of 4-chloromethylimidazole hydrochloride in 25 ml. of dimethylformamide as described in Example 1. The mixture was stirred at 80°-90° C. for 1 hour, the solvent was removed by evaporation under vacuum, and wthe residue was worked up as described in Example 1 to obtain 11.87 g. of the free base named in the heading above, m.p. 111°-115° C. dec. The product was triturated twice with portions of diethyl ether, and was dissolved in chloroform. The solution was extracted with water and dried over sodium sulfate. Evaporation of the solvent under vacuum gave 11.84 g. of purified free base, m.p. 111°-115° C.
