Reaction Steps
5-(3-Chlorophenyl)-6-methoxy-2-methylnicotinaldehyde. To a cooled solution, −78° C., of 5-(3-chlorophenyl)-6-methoxy-2-methylnicotinonitrile (500 mg, 1.9 mmol) in DCM (15 mL), under nitrogen, was added diisobutylaluminium hydride (1 M in hexanes, 4.8 mL, 4.8 mmol) drop-wise, over 3 minutes. The reaction mixture was stirred at −78° C. for 1 h. The reaction was carefully quenched by addition of saturated sodium fluoride (1 mL). After stirring for 30 minutes the suspension was filtered and the filtrate concentrated under reduced pressure. Purification (FCC, SiO2, 0-50%, EtOAc/hexanes) afforded the title compound (358 mg, 72%). [M+H]=262.05.
