Reaction Steps

Part C. A solution of ethyl 3-[5-(4-isopropyl-phenyl)-pyridin-3-yl]-benzoate (100 mg) in methanol-water (3 mL/1 mL) is treated with lithium hydroxide hydrate (50 mg), and the solution is heated to 40-50° C. for 12 h. After cooling, the solution is neutralized to pH 7 with 3 N HCl and extracted with ethyl acetate. The extract is washed with brine, dried over sodium sulfate, filtered and evaporated to afford the title compound as a powder (80 mg, 87%), m.p. 155-156° C. 1H NMR (300 MHz, CDCl3): δ 8.93-8.90 (2H, m), 8.44 (1H, s), 8.21-8.19 (2H, m), 7.89 (1H, d, J=7 Hz), 7.64 (1H, t, J=8 Hz), 7.61 (2H, d, J=9 Hz), 7.39 (2H, d, J=9 Hz), 3.00 (1H, heptet, J=7 Hz), 1.30 (6H, d, J=7 Hz). MS (ES+): m/e 319 (22), 318 (100).
