Reaction Steps

{7-[5-Chloro-4-(2-methylsulfamoyl-phenylamino)-pyrimidin-2-ylamino]-2-oxo-2,3,4,5-tetrahydro-benzo[b]azepin-1-yl}-acetic acid (227 mg, 0.43 mmol), N-methylpiperazine (48 μl, 0.43 mmol), 1-[3-(dimethylamino)propyl]3-ethylcarbodiimide hydrochloride (98 mg, 0.51 mmol), N-methylmorpholine (119 μl, 2.5 mmol), and hydroxybenzotriazole (69 mg, 0.51 mmol) were dissolved in anhydrous DMF, and the solution was stirred 18 hours at room temperature. It was then partitioned between ethyl acetate and water, and washed once with aqueous sodium bicarbonate and once with water. Concentration afforded a yellow foam. Preparative TLC (10% MeOH/CH2Cl2) gave 2-(5-Chloro-2-{1-[2-(4-methyl-piperazin-1-yl)-2-oxo-ethyl]-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-7-ylamino}-pyrimidin-4-ylamino)-N-methyl-benzenesulfonamideas a white solid, 147 mg. (56% yield) 1H NMR (400 MHz, DMSO-d6) δ 9.51 (s, 1H), 9.27 (s, 1H), 8.43-8.51 (m, 1H), 8.23 (s, 1H), 7.70-7.83 (m, 2H), 7.58-7.64 (m, 1H), 7.41-7.48 (m, 2H), 7.23-7.30 (m, 1H), 7.08-7.12 (m, 1H), 4.58 (s, 2H), 3.34-3.43 (m, 4H), 2.62-3.10 (m, 2H), 2.39 (s, 3H), 1.96-2.32 (m, 11H); MS (m/e) 613 (M+1); retention time 5.99 minute; mp 148-151° C.
