Procedure

To a mixture of 2-(8-amino-1-dimethylcarbamoylmethyl-7-methoxy-2-oxo-1,2,3,5-tetrahydro-benzo[e][1,4]diazepin-4-yl)-N,N-dimethyl-acetamide (80 mg, 0.21 mmol) and 2-(2,5-dichloro-pyrimidin-4-ylamino)-N,N-dimethyl-benzenesulfonamide (69 mg, 0.20 mmol) in isopropanol (5 mL) was added 10-camphorsulfonic acid (123 mg, 0.53 mmol). The mixture was heated to 90° C. for 20 minutes under microwave irradiation, cooled to room temperature, and concentrated on a rotary evaporator. The residue was dissolved in dichloromethane and stirred with saturated aqueous sodium bicarbonate to neutral pH. The organic phase was washed with brine, dried over magnesium sulfate, filtered and concentrated. The crude product was purified by flash chromatography over silica gel (MeOH/DCM) to give 40 mg (29%) of 2-{8-[5-chloro-4-(2-dimethylsulfamoyl-phenylamino)-pyrimidin-2-ylamino]-1-dimethylcarbamoylmethyl-7-methoxy-2-oxo-1,2,3,5-tetrahydro-benzo[e][1,4]diazepin-4-yl}-N,N-dimethyl-acetamide as a pale yellow solid; NMR (400 MHz, CDCl3) δ 9.39 (s, 1H), 8.51 (d, J=8 Hz, 1H), 8.34 (s, 1H), 8.19 (s, 1H), 7.90 (d, J=8 Hz, 1H), 7.61 (s, 1H), 7.56 (m, 1H), 7.28 (m, 1H), 6.94 (s, 1H), 4.45 (br s, 2H), 4.08 (s, 2H), 3.93 (s, 3H), 3.54 (s, 2H), 3.35 (s, 2H), 3.10 (s, 3H), 3.00 (s, 3H), 2.96 (s, 2H), 2.91 (s, 3H), 2.79 (s, 6H); MS (m/e) 689 (M+1); mp 154° C.
