Reaction Steps
(R)-3-(7-Amino-1,2,4,5-tetrahydro-benzo[d]azepin-3-yl)-1,1,1-trifluoro-propan-2-ol (82 mg, 0.30 mmol), N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methanesulfonamide (95 mg, 0.28 mmol), and 4.00 M of Hydrogen chloride in 1,4-Dioxane (0.20 mL) were combined in 2-Methoxyethanol (2.5 mL) and heated at 120° C. After two hours, the mixture was cooled to room temperature, then diluted with 10 mL ethyl ether. A mixture of solids and gum formed, which was intractable, so the mixture was further diluted with 10 mL DCM and Macroporous carbonate resin (3.16 mmol/g loading; 0.75 g, 2.37 mmol) was added, stirred for 4 h then filtered and concentrated in vacuo to afford an oil, which was chromatographed (ISCO, 2×12 g, 0-5% MeOH:DCM). The product elutes with 5% MeOH, to give N-((1R,2R)-2-{5-Chloro-2-[3-((R)-3,3,3-trifluoro-2-hydroxy-propyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino]-pyrimidin-4-ylamino}-cyclohexyl)-methanesulfonamide (145 mg, 90%) as an off white foam.
