Reaction Steps

8-Methoxy-3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (165 mg, 0.000659 mol), N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methanesulfonamide (220 mg, 0.00066 mol), 4 M of Hydrogen chloride in 1,4-Dioxane (200 uL) and Isopropyl alcohol (6.6 mL, 0.086 mol) were combined in a microwave vessel. Heat at 130° C. for 20 min. The mixture was treated with 500 mgs of MP-carbonate resin and stirred for 20 min. The mixture was filtered and concentrated and put on high vac overnight. The crude solid was dissolved in DCM and purified on an ISCO column (40 g, SiO2, 100% DCM to MeOH/DCM gradient) to afford N-((1R,2R)-2-{5-Chloro-2-[8-methoxy-3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino]-pyrimidin-4-ylamino}-cyclohexyl)-methanesulfonam (99 mg, 48%). MP: 92-94° C. 1H-NMR (CDCl3, 400 MHz): 1H-NMR (CDCL3) δ 7.96 (s, 1H), 7.32 (s, 1H), 6.67 (s, 1H), 5.37-5.31 (m, 2H), 3.99-3.95 (broad m, 1H), 3.88 (s, 1H), 3.56 (br s, 2H), 3.38 (s, 1H), 3.28-3.24 (m, 1H), 2.99-2.70 (complex series of m, 11H), 2.26-2.20 (m, 2H), 1.88-1.80 (m, 2H), 1.41-1.28 (m, 6H), 0.92-0.85 (m, 2H). LC/MS: 552.92 (M+H).
