Reaction Steps

To a solution of methyl [5-(4-{5-[(4-fluorophenyl)methyl]pyrimidin-4-yl}-2,3,4,5-tetrahydro-1,4-benzoxazepin-7-yl)-3H-imidazo[4,5-b]pyridine-2-yl]carbamate (0.70 g, 0.129 mmol) in methanol (3 mL) was added 2 M aqueous potassium hydroxide (3 mL) and the mixture was heated at 100° C. for 1 hour. After cooling to room temperature the reaction mixture was concentrated and then diluted with water (5 mL) and the pH adjusted to 9 with 1 M hydrochloric acid. The resulting precipitate was collected by filtration, dissolved in a minimum of methanol and purified by preparative reverse phase HPLC to afford 5-(4-{5-[(4-fluorophenyl)methyl]-6-methylpyrimidin-4-yl}-2,3,4,5-tetrahydro-1,4-benzoxazepin-7-yl)-3H-imidazo[4,5-b]pyridin-2-amine (0.0283 g, 46% yield. 1H NMR (400 MHz, methanol-d4): 8.45 (s, 1H), 7.75 (d, 1H), 7.51 (d, 1H), 7.17 (d, 1H), 7.11-7.06 (m, 3H), 7.01-6.96 (m, 3H), 4.55 (s, 2H), 4.30 (t, 2H), 4.00 (s, 2H), 3.89 (t, 2H), 2.22 (s, 3H); MS (EI) for C27H24FN7O: 482 (MH+)
