Procedure

N-(2-Cyano-ethyl)-2-(2,5-dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (101 mg, 0.288 mmol), 7-Amino-1-methyl-1,3,4,5-tetrahydro-1-benzazepin-2-one (48 mg, 0.25 mmol), and 10-Camphorsulfonic acid (5.0 mg, 0.022 mmol) in Isopropyl alcohol (2.0 mL) were added into a microwave vial and irradiated at 120° C. for 30 min. The reaction was diluted with satd. sodium bicarbonate (5 mL) and cooled to aid in precipitate formation. The solids were collected and washed with 7 mL water. The solids contained product with starting chloropyrimidine and another impurity. The filtrate contained the aniline component, product and other impurities. The filtrate was extracted 3×10 mL DCM, dried and concentrated. The solids were chromatographed (ISCO, 12 g silica gel, 0-100% EtOAc:Hex) separately from the filtrate, and clean fractions were combined to give the product as a yellow foam (44 mg, 35%). LCMS: 504 (M+H), 1H-NMR (CDCl3): 8.93 (s, 1H), 8.34 (d, 1H, J=8.2 Hz), 8.10 (s, 1H), 7.44 (m, 3H), 7.37 (d, 1H, J=7.8 Hz), 7.18 (dd, 1H, J=7.4, 7.4 Hz), 7.07 (d, 1H, J=8.3 Hz), 6.95 (s, 1H), 3.81 (br s, 2H), 3.33 (s, 3H), 3.20 (s, 3H), 2.81 (br s, 2H), 2.64 (m, 2H), 2.32 (t, 2H, J=7.2 Hz), 2.15 (m, 2H).
