実験手順

Triethylamine (0.259 mL, 1.86 mmol) was added to a solution of tert-butyl (3R,6S)-6-(2,3-difluorophenyl)-2-hydrazonoazepan-3-ylcarbamate from Step A (548 mg, 1.55 mmol), 3,3,3-trifluoropropionic acid (0.205 mL, 2.32 mmol), EDC (356 mg, 1.86 mmol), and 1-hydroxy-7-azabenzotriazole (253 mg, 1.86 mmol) in dichloromethane (55 mL). After 18 h, saturated aqueous NaHCO3 was added and the mixture was extracted with CH2Cl2 (3×). The combined organic extracts were dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by silica gel chromatography, eluting with a gradient of CH2Cl2:MeOH—100:0 to 96:4, to give the title compound. MS: m/z=447 (M+1).
