Reaction Steps

A mixture of 5-[4-(6,6-dimethyl-5,6,7,8-tetrahydroquinazolin-4-yl)-2,3,4,5-tetrahydro-1,4-benzoxazepin-7-yl]pyridine-2,3-diamine (174 mg, 0.42 mmol) and 1,3-bis(methoxycarbonyl)-2-methyl-2-thiopseudourea (86 mg, 0.42 mmol) in acetic acid (5 mL) was stirred at 80° C. for 10 h. After cooling to room temperature the mixture was concentrated, methanol (10 mL) was added, the precipitate was filtered off, and lyophilized from a mixture of acetonitrile (2 mL), water (6 mL), and 1N hydrochloric acid (0.25 mL) to give the hydrochloride salt of the title Compound (107 mg, 48% yield) as a yellow solid. 1H NMR (400 MHz, methanol-d4): 8.53 (m, 2H), 8.35 (s, 1H), 7.78 (s, 1H), 7.58 (d, 1H), 7.10 (d, 1H), 5.18 (s, 2H), 4.49 (m, 2H), 4.34 (m, 2H), 3.93 (s, 3H), 2.86 (m, 2H), 2.61 (s, 2H), 1.71 (m, 2H), 0.95 (s, 6H); MS (EI) for C27H29N7O3: 500 (MH+).
