Reaction Steps

To a solution of 3-(1-cyclopropylmethyl-3-p-tolyl-piperidin-3-yl)-phenol (65 mg, 0.15 mmol) in CH2Cl2 (2 ml) at room temperature were added DMAP (18 mg, 0.15 mmol), triethylamine (0.071 mL, 0.52 mmol) and propionyl chloride (0.038 mL, 0.45 mmol). The reaction mixture was stirred at room temperature for 12 hours. The reaction was partitioned between 5 mL CH2Cl2 and 5 mL of aqueous saturated NaHCO3. The aqueous layer was washed with CH2Cl2 (3×5 mL), dried over Na2SO4 and concentrated. Purification by flash chromatography with hexanes/EtOAc (1:1) afforded 58 mg of propionic acid 3-(1-cyclopropylmethyl-3-p-tolyl-piperidin-3-yl)-phenyl ester. 1HNMR (400 MHz, CDCl3) δ 7.33 (d, 2H), 7.26-7.19 (comp, 3H), 7.16-7.03 (comp, 2H), 6.89-6.86 (m, 1H), 3.59-3.43 (comp, 2H), 3.35-3.19 (comp, 2H), 2.59-2.53 (q, 2H), 2.52-2.41 (comp, 2H), 2.27-2.18 (comp, 4H), 1.57-1.44 (comp, 2H), 1.31-1.19 (t, 3H), 1.18-1.09 (comp, 3H), 1.08-1.01 (comp, 3H), 100-0.91 (m, 1H), 0.59-0.49 (comp, 2H), 0.19-0.11 (comp, 1H); MS (M+1) 463.3.
