37% | With N-ethyl-N,N-diisopropylamine; In acetonitrile; at 85℃;Inert atmosphere; | Under argon, a solution of 3-chloro-5-(2,6-dimethoxyphenyl)-1,2,4-triazine (15.4 mg, 0.061 mmol, prepared as in example 41), <strong>[51785-22-9]2-piperidin-2-yl-1,3-benzothiazole</strong> (20 mg, 0.092 mmol) and DIPEA (11 µL, 0.063 mmol) in anhydrous acetonitrile (0.25 mL) was stirred at 85C overnight. The solution was then concentrated and the residue was purified by preparative TLC (silica gel, dichloromethane/methanol 95/5) to give 2-{1-[5-(2,6-dimethoxyphenyl)-1,2,4-triazin-3-yl]piperidin-2-yl}-1,3-benzothiazole (9.8 mg, 37%) as a yellow oil. ESI-MS m/z 434 (M+H)+. 1H NMR (CDCl3), δ (ppm): 8.59 (s, 1H), 7.99 (d, J = 7.8 Hz, 1H), 7.83 (d, J = 7.8 Hz, 1H), 7.45 (t, J = 8.4 Hz, 1H), 7.39-7.32 (m, 2H), 7.60 (d, J = 8.4 Hz, 2H), 6.55 (br s, 1H), 5.04-5.00 (m, 1H), 3.67 (s, 6H), 3.36-3.28 (m, 1H), 2.79-2.74 (m, 1H), 2.06-2.02 (m, 1H), 1.80-1.69 (m, 4H). |
