실험 절차

Pentanoic acid (0.37 g), N,N-diisopropyl-ethylamine (1.51 mL) and N-[(dimethylamino)-1H-1,2,3-triazolo-[4,5-b]pyridin-1-yl-methylene]-N-methyl-methanaminium hexafluoro-phosphate N-oxide (1.66 g) were mixed in dry N,N-dimethylformamide (3 mL) and stirred under argon for 2 minutes. 2,6-Dimethyl-4-morpholin-4-yl-phenylamine (0.50 g) dissolved in dry N,N-dimethylformamide (2 mL) was added to the reaction mixture, which was stirred at 25° C. under argon for 16 hours. Ethyl acetate (20 mL) was added and the organic phase was washed with saturated aqueous ammonium chloride/water (1:1, 20 mL), water (20 mL), brine/water (1:1, 20 mL), dried over magnesium sulfate, concentrated in vacuo and purified by flash chromatography to furnish 0.28 g (40% yield) of the title compound as a white solid. LC-MS (m/z) 291 (MH+); tR=1.61, (UV, ELSD) 99%, 99%. 1H NMR (500 MHz, DMSO-d6): 0.91 (t, 3H), 1.34 (m, 2H), 1.58 (qui, 2H), 2.06 (s, 6H), 2.27 (t, 2H), 3.04 (t, 4H), 3.71 (t, 4H), 6.62 (s, 2H), 8.94 (s, 1H).
