Procedure

A solution of 2-(nonyloxy)isonicotinonitrile (250 mg, 1.0 mmol, 1 equiv.) and sodium methoxide (10 mg, 0.1 mmol, 0.1 equiv.) in dry CH3OH (10 ml) was stirred at r.t. for 2.5 h. A solution of lithium hydroxide (24 mg, 1.0 mmol, 1 equiv.) in water (1 ml) was added and the reaction mixture was heated under reflux for 3.5 h. After cooling at r.t., the mixture was poured into water (40 ml). The precipitant solid was filtered and dried in vacuo at 50° C., to give the desired compound as a white solid (60 mg, 23%), mp 108-110° C. HPLC-MS (method 1): m/z 265 [M+H]+, Rt=5.08 min.
