Participants

Reaction Steps

To a solution of methyl 1-((5-(3-chlorophenyl)-6-methoxypyridin-3-yl)methyl)-1H-1,2,4-triazole-3-carboxylate (Example 141, 103 mg, 0.28 mmol) in methanol (2 mL) was added ammonia in methanol (2 mL of 7N solution, 14 mmol). The mixture was heated using microwave irradiation at 130° C. for 20 min. The LC/MS showed incomplete conversion. To the reaction mixture was added more ammonia in methanol (2 mL, 14 mmol) and irradiated in a microwave at 120° C. for an additional 20 min. The solvent was removed under reduced pressure. Purification (FCC, SiO2, 0-5% MeOH/DCM) afforded the title compound (77 mg, 77%). 1H NMR (400 MHz, DMSO-d6) δ 8.74 (s, 1H), 8.25 (d, J=2.3 Hz, 1H), 7.85 (d, J=2.3 Hz, 1H), 7.78-7.70 (m, 1H), 7.62-7.40 (m, 5H), 5.45 (s, 2H), 3.87 (s, 3H). [M+H]=354.18.
