Procedure

N-(4-Amino-2,6-dimethyl-phenyl)-2-cyclopentyl-acetamide (207 mg) and 4-trifluoromethyl-benzaldehyde (125 uL) were dissolved in acetonitrile (2 mL) and heated to 150° C. for 5 minutes in a sealed microwave process vial. Sodium cyanoborohydride (0.7 M in methanol, 5 mL) and acetic acid (500 uL) were added and the reaction mixture was stirred at 25° C. for 16 hours. Aqueous sodium carbonate (10%, 25 mL) was added, and the product was collected by filtration to furnish 0.31 g (91% yield) of the title compound as a white solid. LC-MS (m/z) 405 (MH+); tR=3.19, (UV, ELSD) 97%, 99%. 1H NMR (500 MHz, DMSO-d6): 1.19 (m, 2H), 1.51 (m, 2H), 1.60 (m, 2H), 1.75 (m, 2H), 1.96 (s, 6H), 2.22 (m, 3H), 4.34 (d, 2H), 6.18 (t, 1H), 6.25 (s, 2H), 7.55 (d, 2H), 7.67 (d, 2H), 8.76 (s, 1H).
