Versuchsvorschrift

Triethylamine (0.030 mL, 0.215 mmol) was added to a solution of (3R,6S)-3-amino-6-(2,3-difluorophenyl)-1-(2,2,2-trifluoroethyl)azepan-2-one (80 mg, 0.248 mmol) and 4-nitrophenyl chloroformate (44 mg, 0.218 mmol) in tetrahydrofuran (3 mL) at 0° C. After 0.5 h, 7-piperidin-4-yl-7,9-dihydro-8H-purin-8-one hydrochloride (73 mg, 0.248 mmol) and triethylamine (0.120 mL, 0.860 mmol) were added and the mixture allowed to warm to ambient temperature. After 18 h, the mixture was partitioned between ethyl acetate and water. The organic layer was washed with water (2×), saturated brine, dried over magnesium sulfate, filtered and concentrated. Purification by silica gel chromatography (100% dichloromethane→95% dichloromethane/methanol) gave the title compound (114 mg). MS 567.2123 (M+1).
