反応手順

(2,5-Dichloro-pyrimidin-4-yl)-(3-morpholin-4-yl-phenyl)-amine (96 mg, 0.29 mmol) was added into a vial, followed by a solution of 3-Ethyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (52 mg, 0.27 mmol) in 2-Methoxyethanol (2.7 mL). 4 M of Hydrogen chloride in 1,4-Dioxane (0.10 mL) was added and the reaction was heated at 120° C. After 6 h, the reaction was cooled and Macroporous carbonate resin (3.16 mmol/g loading; 400 mg, 1.25 mmol) was added and the reaction was stirred overnight, then was concentrated in vacuo onto Celite, and chromatographed (24 g alumina column, EtOAC-5% MeOH: EtOAC-5% MeOH:DCM). 5-Chloro-N*2*-(3-ethyl-2,3,4,5-tetrahydro-1H-benzo-[d]azepin-7-yl)-N*4*-(3-morpholin-4-yl-phenyl)-pyrimidine-2,4-diamine was isolated as a yellow foam (64 mg, 49%). LCMS (m/e) 479 (M+1); 1H-NMR (CDCl3, 400 MHz) δ 8.01 (s, 1H), 7.47 (m, 2H), 7.37 (d, 1H, J=2.0 Hz), 7.14 (dd, 1H, J=2.3, 8.1 Hz), 6.96 (d, 1H, J=7.9 Hz), 6.92 (m, 3H), 6.82 (s, 1H), 3.89 (t, 4H, J=4.8 Hz), 3.16 (t, 4H, J=4.8 Hz), 2.85 (m, 4H), 2.63 (m, 4H), 2.57 (q, 2H, J=7 Hz), 1.10 (t, 1H, J=7 Hz).
