Procedure
Combined 7-Amino-1-ethyl-8-methoxy-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (124.8 mg, 0.0005327 mol), N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methanesulfonamide (180 mg, 0.00053 mol), 4 M of Hydrogen chloride in 1,4-Dioxane (200 uL) and heat in a Radley tube for 4.5 h at 110° C. Cool to RT and then treated with xs solid MP-carbonate resin and stirred for 30 min. Filtration, followed by concentration afforded a gummy solid that was put on high-vac overnight. The mixture was purified by ISCO chromoatography (40 g SiO2, 30% EA/hexane to 100% EA) afforded N-{(1R,2R)-2-[5-Chloro-2-(1-ethyl-8-methoxy-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-7-ylamino)-pyrimidin-4-ylamino]-cyclohexyl}-methanesulfonamide as an off-white foam that was dried under high vac and broken into a powder (112.41 mg, 39%). MP: 120-128° C. 1H-NMR (DMSO, 400 MHz) δ 8.10 (s, 1H), 7.96 (d, J=1.1 Hz, 1H), 7.69 (s, 1H), 7.18 (d, J=8.3 Hz, 1H), 7.00 (s, 1H), 6.85 (d, J=7.9 Hz, 1H), 3.88-3.83 (m, 1H), 3.35-3.31 (m, 1H), 2.90 (s, 3H), 2.60 (broad s, 2H), 2.11-2.00 (m, 8H), 1.70-1.67 (m, 2H), 1.40-1.15 (m, 5H), 1.00 (t, J=6.9 Hz, 3H); LC/MS: 537.34 (M+H).
