Reaction Steps

2-Methylpropyl 2-(4-{4-[(4-cyanopiperidin-1-yl)carbonyl]-2,3,4,5-tetrahydro-1,4-benzoxazepin-7-yl}phenyl)-1H-imidazole-1-carboxylate (296 mg, 0.56 mmol) was taken into methanol (10 mL), THF (2 mL) and water (0.5 mL) then warmed to give a homogeneous solution. Potassium carbonate (160 mg, 1.15 mmol) and the mixture was stirred for 30 minutes. The mixture was then concentrated and partitioned with ethyl acetate and 10% aqueous citric acid. The organic solution was washed with brine, dried over anhydrous sodium sulfate then filtered and concentrated. The residue was purified by silica gel chromatography (10% ethanol in ethyl acetate) to give 1-({7-[4-(1H-imidazol-2-yl)phenyl]-2,3-dihydro-1,4-benzoxazepin-4(5H)-yl}carbonyl)piperidine-4-carbonitrile (155 mg, 65% yield). 1H NMR (400 MHz, d4-methanol): 7.92 (d, 2H), 7.69 (d, 2H), 7.56 (d, 1H), 7.51 (dd, 1H), 7.15 (s, 2H), 7.04 (d, 1H), 4.51 (s, 2H), 4.21 (tr, 2H), 3.70 (tr, 2H), 3.49-3.43 (m, 2H), 3.13 (m, 2H), 2.97 (m, 1H), 1.98-1.93 (m, 2H), 1.86-1.78 (m, 2H). MS (EI) for C25H25N5O2: 429 (MH+).
