Reaction Steps

To a solution of ethyl nicotinate (10 g) and phenylacetonitrile (5.1 g) in tert-butyl alcohol (30 mL), was added potassium tert-butoxide (6.4 g), and the mixture was stirred at 100° C. for 3 h. After cooling, the resulting mixture was dissolved in water and washed with isopropyl ether. The aqueous phase was adjusted to pH 7.0 with 2 N hydrochloric acid and extracted with ethyl acetate. The extracts were washed with water, dried, and the solvent was evaporated. The crystalline residue was recrystallized from ethyl acetate-isopropyl ether to obtain the title compound (6.0 g, yield 62%).
