Reaction Steps

7-Amino-1-methyl-1,3,4,5-tetrahydrobenzo[b]azepin-2-one (166 mg, 0.87 mmol) and 2-(2,5-dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (259 mg, 0.87 mmol) were suspended in 2-methoxyethanol (9 ml), and heated to 120° C. for 18 hours. Concentration afforded a brown residue. Purification by preparative TLC (5% MeOH/CH2Cl2) gave a slightly impure yellow oil which was then triturated with acetone to give the title compound as a white solid, 45 mg. (11% yield) 1H NMR (400 MHz, DMSO-d6) δ 11.58 (s, 1H), 9.52 (s, 1H), 8.64-8.81 (m, 2H), 8.22 (s, 1H), 7.69-7.75 (m, 1H), 7.42-7.59 (m, 3H), 7.12-7.26 (m, 2H), 3.19 (s, 3H), 2.74-2.80 (m, 2H), 2.49-2.60 (m, 2H), 1.95-2.20 (m, 5H); MS (m/e) 451 (M+1); mp 244-246° C.
