3-(2-Methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (76 mg, 0.34 mmol) and trans-2-(2,5-dichloro-pyrimidin-4-ylamino)-cyclohexanol (100 mg, 0.38 mmol, 1.1 eq) were dissolved in IPA (3 mL). 4.0 M HCl in dioxane (95 μL, 0.38 mmol, 1.1 eq) was added and the reaction was heated at 140° C. in a microwave for 2.5 hours. The reaction was then concentrated under reduced pressure and the residue was taken up in CH2Cl2 (20 mL) and washed with sat. NaHCO3 (20 mL). The organic layer was dried (sodium sulfate), filtered, and concentrated under reduced pressure. Purification by basic alumina chromatography using a gradient of 0-100% EtOAc/hex as the eluting solvent to obtain trans-2-{5-chloro-2-[3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino]-pyrimidin-4-ylamino}-cyclohexanol as a pink foam (42 mg, 28%).
