Participants

Reaction Steps

Dichloromethane (2 mL) was added to 7-[6-(1H-imidazol-2-yl)pyridin-3-yl]-2,3-dihydro-1,4-benzoxazepin-4(5H)-carbonyl chloride was obtained in step 4 followed by diisopropylethylamine (0.12 mL, 0.65 mmol) and 4-cyanopiperidine hydrochloride (25 mg, 0.16 mmol). The mixture was stirred at room temperature for 30 min and then concentrated. Purification of the residue by preparative reverse phase HPLC (0.1% aqueous ammonium acetate-acetonitrile) provided the title compound (18 mg, 32% yield) as a colorless solid. 1H NMR (400 MHz, DMSO-d6): 12.84 (br. S, 1H), 8.86 (d, 1H), 8.11 (m, 2H), 7.71 (d, 1H), 7.61 (dd, 1H), 7.25 (br. s, 1H), 7.10 (br. s, 1H), 7.06 (d, 1H), 4.49 (s, 2H), 4.23 (m, 2H), 3.61 (m, 2H), 3.30 (m, 2H), 3.00 (m, 3H), 1.87 (m, 2H), 1.73 (m, 2H); MS (EI) for C24H24N6O2: 429 (MH+).
