実験手順

The mixture of 2-chloro-N-(5-cyclopropyl-1H-pyrazol-3-yl)pyrimidin-4-amine (150 mg, 0.64 mmol, 1.0 equiv.), 3-aminobenzenesulfonamide (329 mg, 1.91 mmol, 3.0 equiv.), butan-1-ol (1 mL) and dioxane (0.5 mL) was stirred at 95° C. for 8 h. Then, the reaction mixture was cooled to room temperature and filtered. The residue was crystallized with methane/water/isopropyl ether to afford Compound 82 (7.7 mg, 3%). LC-MS (m/z): 372.1 [M+H]+; 1H NMR (400 MHz, DMSO-d6): δ 0.62-0.63 (m, 2H), 0.88-0.92 (m, 2H), 1.82-1.86 (m, 1H), 6.06 (bs, 1H), 6.49 (bs, 1H), 7.39 (s, 2H), 7.52 (d, J=1.8 Hz, 2H), 7.97 (s, 3H), 10.02 (s, 1H), 10.45 (bs, 1H), 12.27 (bs, 1H).
