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 chromatography (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%).
