Reaction Steps

N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-2,2,2-trifluoro-acetamide (204 mg, 0.571 mmol) was added into a Vial, followed by a solution of 3-Ethyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (106 mg, 0.557 mmol) in 2-Methoxyethanol (7 mL). 4 M of Hydrogen chloride in 1,4-Dioxane (0.2 mL) was added and the reaction was heated at 120° C. After 7 h, the reaction was cooled to room temperature, Macroporous carbonate resin (3.16 mmol/g loading; 530 mg, 1.68 mmol) was added and stirred 30 min. The polymer was filtered off, and the solvent removed in vacuo. The residue was dissolved in DCM, then chromatographed (2×12 g SiO2, ISCO, 0-10% MeOH:DCM) to afford N-{(1R,2R)-2-[5-Chloro-2-(3-ethyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino)-pyrimidin-4-ylamino]-cyclohexyl}-2,2,2-trifluoro-acetamide (128 mg, 45%) as a beige solid. m.p.=165° C.; LCMS (m/e) 511 (M+1); 1H-NMR (CDCl3, 400 MHz) δ 7.98 (s, 1H), 7.94 (s, 1H), 7.32 (m, 2H), 7.08 (d, 1H, J=8.1 Hz), 6.93 (s, 1H), 5.27 (d, 1H, J=7.4 Hz), 3.99 (m, 1H), 3.87 (m, 1H), 3.68 (m, 3H), 3.11 (m, 2H), 2.7-2.9 (m, 4H), 2.30 (d, 1H, J=11.4 Hz), 2.16 (d, 1H, J=11.7 Hz), 1.8-1.9 (m, 2H), 1.2-1.6 (m, 8H).
