Versuchsvorschrift

A mixture of 4-(fluoromethyl)piperidine-1-carbonyl chloride (reagent preparation 37) (24 mg, 0.13 mmol), methyl [6-(2,3,4,5-tetrahydro-1,4-benzoxazepin-7-yl)-1H-imidazo[4,5-b]pyridin-2-yl]carbamate hydrochloride (34 mg, 0.091 mmol), and diisoproylethylamine (59 mg, 0.45 mmol) in dichloromethane (0.5 mL) and N,N-dimethylformamide (0.5 mL) was stirred at room temperature for one hour. The reaction mixture was concentrated then dissolved in methanol (2 mL) and purified directly by preparative reverse phase HPLC to give methyl [6-(4-{[4-(fluoromethyl)piperidin-1-yl]carbonyl}-2,3,4,5-tetrahydro-1,4-benzoxazepin-7-yl)-1H-imidazo[4,5-b]pyridin-2-yl]carbamate, (21 mg, 48% yield), (400 MHz, DMSO-d6): 8.41 (br, 1H), 7.87 (s, 1H), 7.54 to 7.44 (m, 2H), 7.05 (d, 1H), 4.45 (s, 2H), 4.31 (dd, 2H), 4.19 (m, 2H), 3.67 to 3.55 (m, 4H), 2.74 (t, 2H), 1.84 (br, 1H), 1.67 to 1.58 (m, 2H), 1.29 to 1.18 (m, 2H); MS (EI) for C24H27FN6O4: 483 (MH+).
