Participants

Reaction Steps

Triethylamine (43 μL, 0.310 mmol) was added to a solution of the bis hydrochloride salt of (6S,9R)-6-(2,3-difluorophenyl)-3-(tetrahydrofuran-3-yl)-6,7,8,9-tetrahydro-5H-imidazo[1,2-a]azepin-9-amine (42 mg, 0.103 mmol) and 4-nitrophenyl chloroformate (21 mg, 104 mmol) in tetrahydrofuran (3 mL) at 0° C. After 30 min, 2-oxo-1-piperidinium-4-yl-2,3-dihydro-1H-imidazo[4,5-b]pyridin-4-ium dichloride (45 mg, 0.155 mmol), triethylamine (43 μL, 0.310 mmol) and dichloromethane (3 mL) were added and the mixture allowed to warm to ambient temperature. After 18 h, the reaction was concentrated. Purification by reverse phase HPLC (C-18, 90% water/acetonitrile→100% acetonitrile with 0.1% trifluoroacetic acid) gave the title compound (35 mg). MS 578.2702 (M+1).
