Reaction Steps
To a solution of 2-chloro-4-(4-pyridyl)thiazole (1.00 g, 0.005 mol) and benzylcyanide (1.18 g, 0.010 mol) in dry toluene (10 mL) at 5° C. was added sodamide (400 mg, 0.010 mol) and the mixture heated to 100° C. for 20 minutes. After cooling, the mixture was quenched with water, the layers separated, and the aqueous phase washed with methylene chloride (2×50 mL). The combined extracts were dried over sodium sulfate, concentrated, and chromatographed through silica gel (3:1 ethyl acetate/methylene chloride as eluant). After decolorizing with charcoal, recrystallization from hexane/ethyl acetate afforded 2-phenyl-2-[4-(4-pyridyl)-2-thiazolyl]acetonitrile (115 mg, 8%). mp. 110°-111° C.
