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 N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methane sulfonamide (90 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 130° C. in the microwave for 30 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 followed by 0-20% MeOH in EtOAc) to obtain N-{(1R,2R)-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]-cyclohexyl}methanesulfonamide as a beige foam (27 mg, 22%). LCMS: m/z=510.20 (M+H+); 1H NMR (400 MHz, CDCl3) δ 8.48 (m, 2H), 7.96 (s, 1H), 7.27 (m, 2H), 5.60 (m, 2H), 3.95 (m, 1H), 3.34 (m, 5H), 3.20 (s, 3H), 2.86 (s, 3H), 2.78 (s, 3H), 2.24 (m, 2H0, 1.83 (m, 2H), 1.39 (m, 4H).
