Procedure

Into a microwave vial, (2,5-dichloro-pyrimidin-4-yl)-[2-(2-morpholin-4-yl-ethoxy)-phenyl]-amine (100.0 mg, 0.2708 mmol), 8-amino-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (61.2 mg, 0.348 mmole), isopropyl alcohol (2.00 mL, 26.1 mmol) and 4 M of hydrogen chloride in 1,4-dioxane (0.20 mL) were added, respectively. The reaction was heated in the microwave on 300 watts, 120° C. for 20 minutes. Triethylamine (0.2 mL) was added. The reaction was concentrated to dryness. The desired product was isolated via ISCO column chromatography with DCM and methanol as eluant (10% methanol). The resulting solid was triturated with diethyl ether to afford 8-{5-Chloro-4-[2-(2-morpholin-4-yl-ethoxy)-phenylamino]-pyrimidin-2-ylamino}-1,3,4,5-tetrahydro-benzo[b]azepin-2-one as a white solid (42 mg, 30%). 1H-NMR (DMSO-D6, 400 MHz): δ 9.42 (s, 1H), 9.32 (s, 1H), 8.25 (s, 1H), 8.18 (s, 1H), 8.10 (bs, 1H), 7.35 (d, 1H), 7.27 (s, 1H), 7.12 (s, 2H), 7.0 (d, 1H), 6.85-6.95 (m, 1H), 4.16 (t, 2H), 3.50 (t, 4H), 2.55-2.70 (m, 4H), 2.40 (s, 4H), 2.00-2.20 (m, 4H). LC/MS (ESI+) 509 (M+H).
