An alkaline hydrolysis procedure may also be used to synthesize the desired compound. Accordingly, 2-amino-5-(4-chlorophenyl)-3-pyridinecarbonitrile (2.0 grams) and KOH (2.0 grams) in 30 ml ethylene glycol were heated at 150° C. in an oil bath. After 3 hours the reaction was complete and the alkaline solution was poured into ice water and acidified to give the desired solid. The final product was again confirmed by NMR, yield 2.3 grams, m.p. 300°-315° C. dec.
