A solution of 7-amino-1,2,4,5-tetrahydro-(2,4)-benzodiazepin-3-one (75.0 mg, 0.42 mmol) in isopropanol (3 mL) was treated with N-[2-(2,5-Dichloro-pyrimidin-4-ylamino)-phenyl]-methanesulfonamide (140.2 mg, 0.42 mmol) and 4N HCl/Dioxane (0.106 mL, 0.50 mmol). The reaction mixture was irradiated at 130° C. for a total of 60 minutes. The reaction mixture was then reduced en vacuo and the product was purified and isolated flash column chromatography (0% MeOH/DCM-15% MeOH/DCM) to afford 1.98 mg of N-{2-[5-Chloro-2-(3-oxo-2,3,4,5-tetrahydro-1H-benzo[e][1,3]diazepin-7-ylamino)-pyrimidin-4-ylamino]-phenyl}-methanesulfonamide as the HCl salt. The compound was isolated as a foam, LC/MS (ESI)=480.35 (M+H). 1H NMR (400 MHz, MeOD, d4) δ 7.68 (m, 2H), 7.46 (m, 1H), 7.29 (m, 2H), 7.06 (m, 4H), 6.62 (m, 1H), 4.31 (m, 2H), 4.19 (m, 2H), 3.47 (s, 1H), 3.12 (s, 1H), 2.92 (s, 3H).
