Reaction Steps

9-Amino-1,4-dimethyl-1,2,3,4-tetrahydro-benzo[e][1,4]diazepin-5-one (#) (50 mg, 0.24 mmol) and 2-(2,5-Dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (#) (79 mg, 0.27 mmol) were combined in isopropanol (1 mL). 4 N HCl in dioxane (67 μL) was added, and the resulting mixture was heated to 110° C. in the microwave for 20 min. The resulting solution was diluted with CH2Cl2 (50 ml) washed with saturated aqueous NaHCO3 (2×50 ml), dried over MgSO4, filtered, and concentrated. The resulting residue was purified with silica gel chromatography (0-100% EtOAc in hexanes) to obtain 2-[5-Chloro-2-(1,4-dimethyl-5-oxo-2,3,4,5-tetrahydro-1H-benzo[e][1,4]diazepin-9-ylamino)-pyrimidin-4-ylamino]-N-methyl-benzamide as an off-white solid (47 mg, 41%). mp 243-244° C.; LCMS: m/z=466.16 (M+H+); 1H NMR (400 MHz, CDCl3) δ 11.00 (s, 1H), 8.54 (m, 3H), 8.12 (s, 1H), 7.51 (m, 2H), 7.26 (m, 1H), 7.19 (dd, J=7.8 Hz, 1H), 7.09 (dd, J=7.8 Hz, 1H), 6.42 (d, J=4.5 Hz, 1H), 3.36 (m, 4H), 3.21 (s, 3H), 3.03 (d, J=4.8 Hz, 3H), 2.82 (s, 3H).
