Triethylamine (42 μL, 0.298 mmol) was added to a solution of the bis hydrochloride salt of (6S,9R)-6-(2,3-difluorophenyl)-3-(2,2,2-trifluoroethyl)-6,7,8,9-tetrahydro-5H-[1,2,4]triazolo[4,3-a]azepin-9-amine (50 mg, 0.119 mmol) and 1,1′-carbonyldiimidazole (44 mg, 0.271 mmol) in tetrahydrofuran (4 mL) at 0° C. After 1 h, 1-piperidin-4-ylimidazolidine-2,4-dione (27 mg, 0.149 mmol) and dichloromethane (3 mL) were added and the mixture heated to 60° C. After 2 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 (28 mg). MS 556.2126 (M+1).
