実験手順

(S)-Methyl 2-(4-bromo-1-chloro-8-oxo-9-(2,2,2-trifluoroethyl)-3,6,7,8,9,10-hexahydroazepino[3,4-e]indazol-7-yl)acetate (210 mg, 0.448 mmol) was dissolved in a mixture of tetrahydrofuran (3.0 ml) and methanol (3.0 ml). Water (3.00 ml) was added to the mixture followed by lithium hydroxide hydrate (30 mg, 0.715 mmol). Reaction was warmed to 50° C. and held with stirring for 5 hours. Mixture was cooled to room temperature and allowed to stand for 64 hours. More lithium hydroxide hydrate (24.9 mg, 0.593 mmol) was added to the mixture. Reaction was warned to 50° C. and held for 3 hours. Mixture was cooled to room temperature. Organic solvents were removed from the mixture by roto-vap. Residue was diluted with water. Mixture was neutralized with 1.4 mL 1N hydrochloric acid. Material was extracted twice with ethyl acetate and the aqueous phase was discarded. Organics were dried MgSO4, filtered and then concentrated to dryness. Title compound was obtained as off-white solid in quantitative yield. LCMS (M−H)−=453.9.
