実験手順

To a solution of 5-((1-(tert-butoxycarbonyl)piperidin-4-yl)ethynyl)-3-(ethyl(tetrahydro-2H-pyran-4-yl)amino)-2-methylbenzoic acid (1.06 g, 2.25 mmol) in DMSO (5.8 mL) at rt was added triethylamine (0.90 mL, 6.44 mmol) and (4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methanaminium chloride (0.405 g, 2.15 mmol). The clear solution become heterogenous. Then HOBT (0.493 g, 3.22 mmol) and EDC (0.617 g, 3.22 mmol) were added and the resulting reaction mixture was stirred at rt overnight. The reaction was quenched with water (80 mL) and the slurry was stirred for 1 h at rt. The slurry was filtrated and the cake was washed with water (2×20 mL). The collected solid was dried under vacuum to give the titled compound (1.27 g, 98% yield). 1H-NMR (500 MHz, CD3OD) 8 ppm; 7.22 (s, 1H), 7.08 (d, J=1.0 Hz 1H), 6.11 (s, 1H), 4.45 (s, 2H), 3.92 (brd, J=10.8 Hz, 2H), 3.78 (dd, J=4.4, 5.4 Hz, 1H), 3.75 (dd, J=4.4, 5.4 Hz, 1H), 3.36 (t, J=11.7 Hz, 2H), 3.21 (br t, J=8.3 Hz, 2H), 3.07 (q, J=7.3 Hz, 2H), 3.01 (dddd, J=3.9, 3.9, 11.3, 11.3 Hz, 1H), 2.84 (dddd, J=3.4, 3.4. 3.9, 3.9 Hz, 1H), 2.38 (s, 3H), 2.28 (s, 3H), 2.25 (s, 3H), 1.88 (m, 2H), 1.70 ((brd, J=12.2 Hz, 2H), 1.60 (m, 4H), 1.47 (s, 9H), 0.87 (t, J=7.3 Hz, 3H); MS (ESI) [M+H]+605.6.
