Versuchsvorschrift

N-(4-Amino-2,6-dimethyl-phenyl)-2-cyclopentyl-acetamide (204 mg) and 6-trifluoromethyl-pyridine-3-carbaldehyde (163 mg) were dissolved in acetonitrile (3 mL) and heated to 150° C. for 10 minutes in a sealed microwave process vial. The reaction mixture was concentrated in vacuo, redissolved in methanol (5 mL) followed by addition of acetic acid (0.5 mL) and sodium cyanoborohydride (244 mg) and stirred at 25° C. for 16 hours. Aqueous sodium carbonate (10%, 25 mL) was added, and the product was collected by filtration to furnish 0.311 g (92% yield) of the title compound as a white solid. LC-MS (m/z) 406 (MH+); tR=2.90, (UV, ELSD) 98%, 99%. 1H NMR (500 MHz, DMSO-d6): 1.20 (m, 2H), 1.51 (m, 2H), 1.60 (m, 2H), 1.75 (m, 2H), 1.97 (s, 6H), 2.22 (m, 3H), 4.39 (d, 2H), 6.20 (t, 1H), 6.28 (s, 2H), 7.85 (d, 1H), 7.99 (d, 1H), 8.75 (s, 1H), 8.77 (s, 1H).
