Reaction Steps

A solution of 2-(2-fluoro-4-(piperidin-2-yl)phenyl)benzo[d]oxazole-7-carboxamide (200 mg, 0.44 mmol), 10% Pd/C (100 mg) and propanal (10 ml, 4 mmol) in methanol (10 ml) was hydrogenated at room temperature for two days. The solution was filtered off and concentrated; the residue was purified by prep-HPLC to give 2-(2-fluoro-4-(1-propylpiperidin-2-yl)phenyl)benzo[d]oxazole-7-carboxamide (94 mg, yield 43%). 1H-NMR (400 MHz, CD3OD) δ (ppm): 0.80 (s, 3H), 1.60-1.77 (m, 3H), 1.97-2.13 (m, 5H), 2.86 (s, 2H), 3.18 (s, 1H), 3.78-3.80 (m, 1H), 4.39-4.413 (m, 1H), 7.302-7.43 (m, 1H), 7.50-7.70 (m, 3H), 7.92-7.93 (m, 2H), 8.39 (s, 1H); LC-MS (ESI) m/z: 382 (M+1)+.
