Procedure

Triethylamine (50 μL, 0.356 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 (60 mg, 0.143 mmol) and 1,1′-carbonyldiimidazole (41 mg, 0.25 mmol) in tetrahydrofuran (3 mL) at 0° C. After 25 min, the hydrochloride salt of 3-piperidin-4-yl-3,4-dihydroquinazolin-2(1H)-one (38 mg, 0.143 mmol) and dichloromethane (3 mL) were added and the mixture heated to 60° C. After 16 h, the reaction mixture was allowed to cool to ambient temperature and concentrated. Purification by reverse phase HPLC (C-18, 10% acetonitrile/water→100% acetonitrile with 0.1% trifluoroacetic acid) gave the title compound (54 mg). MS 604.2404 (M+1).
