Reaction Steps

9-Amino-1-methyl-1,2,3,4-tetrahydro-benzo[e][1,4]diazepin-5-one (#) (40 mg, 0.21 mmol) and 2-(2,5-Dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (#) (68 mg, 0.23 mmol) were combined in isopropanol (1 mL). 4 N HCl in dioxane (57 μL) was added, and the resulting mixture was heated to 110° C. in the microwave for 20 min. The resulting mixture was filtered, washed with CH2Cl2 and acetone. The ppt was dissolved in H2O, neutralized with NaHCO3, and extracted with EtOAc, dried over MgSO4, filtered, and concentrated. The resulting residue was purified with silica gel chromatography (0-10% MeOH in CH2Cl2) to obtain 2-[5-Chloro-2-(1-methyl-5-oxo-2,3,4,5-tetrahydro-1H-benzo[e][1,4]diazepin-9-ylamino)pyrimidin-4-ylamino]-N-methyl-benzamide as a white solid (6 mg, 5%). mp 282-284° C.; LCMS: m/z=452.22 (M+H+), 1H NMR (400 MHz, CDCl3) δ 11.30 (s, 1H), 8.41 (d, J=8.8 Hz, 1H), 8.06 (s, 1H), 7.73 (d, J=8.0 Hz, 1H), 7.49 (d, J=7.6 Hz, 1H), 7.42 (d, J=8.0 Hz, 1H), 7.26 (m, 1H), 7.06 (m, 1H), 6.88 (m, 1H), 6.69 (m, 1H), 6.21 (m, 1H), 4.43 (m, 1H), 3.55 (m, 2H), 3.42 (m, 2H), 3.18 (s, 3H), 3.02 (m, 3H).
