実験手順
(S)-Methyl 2-(4-chloro-8-oxo-9-(pyridin-4-ylmethyl)-3,6,7,8,9,10-hexahydroazepino[3,4-e]indazol-7-yl)acetate (21 mg, 0.05 mmol) was dissolved in 1N hydrochloric acid (1.0 mL). Reaction was heated at 50° C. for 5 hours. Another 1 mL of 1N hydrochloric acid was added to the mixture. Reaction was heated at 50° C. for 17 hours. Mixture was concentrated in vacuo. Residue was treated with acetonitrile and then the material was concentrated. Title compound was obtained as dark yellow solid in 83% yield. MS m/e (M+H)+=385.2.
