Reaction Steps
A solution of compound 1-methyl-N-phenylpiperidin-4-amine (1.0 g, 5.255 mmol) in dry CH2Cl2 (10 mL) was treated with Et3N (2.19 mL, 15.766 mmol) followed by 2-bromopropionyl bromide (0.61 mL, 5.780 mmol) at 0° C. and stirred at same temperature for 1 h. The reaction was diluted with water (25 mL) and product was extracted into CH2Cl2 (2×25 mL). The combined CH2Cl2 layer was washed with brine (20 mL) and dried (Na2SO4). Solvent was evaporated and crude was purified by column chromatography (MeOH:CH2Cl2, 5:95) to obtain compound 2-Bromo-N-(1-methylpiperidin-4-yl)-N-phenylpropanamide (1.5 g, 88%) as a solid. 1H NMR (DMSO-d6) δ: 1.09-1.33 (m, 2H), 1.59 (d, 3H, J=6.3 Hz), 1.66-1.74 (m, 2H), 1.89-1.98 (m, 2H), 2.09 (s, 3H), 2.68-2.74 (m, 2H), 4.01 (q, 1H), 4.28-4.36 (m, 1H), 7.26-7.30 (m, 2H), 7.46-7.50 (m, 3H); ESI-MS (m/z, %) 327 and 325 (MH+, 100%).
