Procedure

3-Ethyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (90.9 mg, 0.478 mmol) and N-[2-(2,5-dichloro-pyrimidin-4-ylamino)-ethyl]-methanesulfonamide (150 mg, 0.526 mmol, 1.1 eq) were dissolved in IPA (3 mL). 4.0 M HCl in dioxane (132 μL, 0.526 mmol, 1.1 eq) was added and the reaction was heated at 150° C. in a microwave for 6 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 0-10% MeOH/CH2Cl2 as the eluting solvent to obtain N-{2-[5-chloro-2-(3-ethyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino)-pyrimidin-4-ylamino]-ethyl}-methanesulfonamide as a white solid (90 mg, 43%). m.p.=146° C.; LCMS (m/e) 439 (M+1); 1H-NMR (d6-DMSO, 400 MHz) δ 9.06 (s, 1H), 7.93 (s, 1H), 7.45-7.40 (m, 2H), 7.18-7.08 (m, 2H), 6.97 (d, 1H, J=8.3 Hz), 3.58-3.50 (m, 2H), 3.25-3.14 (m, 2H), 2.89 (s, 3H), 2.82-2.73 (m, 4H), 2.57-2.40 (m, 6H) 1.00 (t, 3H, J=7.2 Hz).
