Reaction Steps

8-Methoxy-3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (55 mg, 0.22 mmol), 2-(2,5-dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (69 mg, 0.23 mmol), and a 4 M solution of hydrogen chloride in dioxane (0.06 mL, 1.1 eq), were added to isopropyl alcohol (2 mL). The reaction mixture was microwaved on 300 watts, at 130° C. for 40 minutes. The reaction mixture was partitioned between aqueous saturated Na2CO3 and dichloromethane, and the aqueous phase was extracted twice with dichloromethane. The combined organic extracts were dried (MgSO4), filtered, and then concentrated on SiO2. Flash chromatography on SiO2 (MeOH/dichloromethane 0-15%) gave 2-{5-Chloro-2-[8-methoxy-3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino]-pyrimidin-4-ylamino}-N-methyl-benzamide as a white solid (47 mg, 42%). MP: 109-112° C.; 1H-NMR (CDCl3) δ 10.98 (s, 1H), 8.65 (d, J=8.4 Hz, 1H), 8.10 (s, 1H), 8.09 (d, J=7.4 Hz, 1H), 7.40-7.54 (m, 3H), 7.07 (d, J=7.6 Hz, 1H), 6.64 (s, 1H), 6.20 (m, 1H), 3.86 (s, 3H), 3.70 (s, 3H), 3.57 (m, 2H), 3.37 (s, 3H), 3.03 (d, J=4.8 Hz, 3H), 2.60-2.98 (m, 10H); LC/MS (ESI+): 510.99 (M+H).
