To a solution of 1-((2-(4-chlorophenyl)-5-methyloxazol-4-yl)methyl)piperidine-4-carboxylic acid (0.25 g, 0.75 mmole), 3-(Azepan-1-yl)propan-1-amine (0.33 g) and DIPEA (0.32 mL) in DMF (5 mL) was added EDC (0.153 g). The reaction solution was stirred at room temperature overnight. The solvent removed and EtOAc (100 mL) was added. The organic layer was washed with saturated sodium bicarbonate (50 mL), water (50 mL) and dried over anhydrous magnesium sulfate. After filtration, the residue after concentration of the filtrate was crystallized from EtOAc/Hexane to provide the N-(3-(azepan-1-yl)propyl)-1-((2-(4-chlorophenyl)-5-methyloxazol-4-yl)methyl)piperidine-4-carboxamide as white solid (0.30 g, 85%). H1NMR (300 MHz, CDCl3), ppm: 7.94 (d, 2H), 7.49 (m, 1H), 7.39 (d, 2H), 3.44 (s, 2H), 3.36 (m, 2H), 2.99 (d, 2H), 2.67 (m, 4H), 2.60 (t, 2H), 2.39 (s, 3H), 2.07 (m, 3H), 1.83 (m, 4H), 1.65 (m, 10H). MS (ESI+) M/z: 473, 475 (M+H).
