Participants

Reaction Steps

A mixture of 2-{[2-(benzyloxy)-4,6-dimethylpyridin-3-yl]methyl}-8-methyl-7-(propan-2-yloxy)-3,4-dihydroisoquinolin-1(2H)-one (107b, 46 mg, 0.10 mmol) and 10% palladium on carbon (10 mg) in methanol (3 mL) was hydrogenated at 1 atmosphere using a balloon for 26 hours. The reaction mixture was filtered through CELITE® then the filtrate was concentrated under vacuum. The residue was purified by column chromatography (EtOAc/heptanes, 50/50-100/0 then EtOAc/MeOH, 100/0-70/30), to give the title compound (Example 107, 27 mg, 74% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ 11.52 (br. s., 1H), 7.05-7.01 (m, 1H), 6.99 (s, 1H), 5.87 (s, 1H), 4.58 (s, 2H), 4.51 (td, J=5.9, 12.1 Hz, 1H), 2.68 (t, J=6.0 Hz, 2H), 2.42 (s, 3H), 2.13 (s, 3H), 2.11 (s, 2H), 1.25 (d, J=5.9 Hz, 6H); MS 355 (M+H).
