Reaction Steps

To a solution of 4-(4-{[4-(6,7-dimethoxy-quinazolin-4-yl)-piperidine-1-carbonyl]-amino}-phenyl)-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (5 mg, 0.009 mmol), as prepared in Example 61, in MeOH (5 mL) was added 10% Pd/C (5 mg). The solution was degassed and was kept stirring under hydrogen atmosphere for 2 h. It was filtered through a pad of celite and the filtrate was evaporated to afford the desired product (3.7 mg, 74% yield). 1H NMR (300 MHz, CD3OD) δ 8.94 (s, 1H), 7.57 (s, 1H), 7.32 (s, 1H), 7.30 (d, J=8.29 Hz, 2H), 7.15 (d, J=8.51 Hz, 2H), 4.35 (m, 2H), 4.20 (m, 2H), 4.06 (s, 3H), 4.03 (s, 3H), 3.91 (m, 1H), 3.21 (m, 2H), 2.85 (br, 2H), 2.67 (m, 1H), 1.93-2.10 (m, 4H), 1.80 (m, 2H), 1.57 (m, 2H), 1.48 (s, 9H). LC-MS (ESI) calcd mass 575.3, found 576.6 (MH+).
