Reaction Steps

(S)-2-(9-neopentyl-8-oxo-3,6,7,8,9,10-hexahydroazepino[3,4-e]indazol-7-yl)ethyl acetate (18 mg, 0.05 mmol) was dissolved in methanol (1 mL). Potassium carbonate (20 mg, 0.14 mmol) was added to the mixture. Reaction stirred at room temperature for 1 hour. Amberlite IRC-50 ion exchange resin was added to the mixture. Reaction stirred at room temperature for 15 minutes. Mixture was filtered. Filtrate was concentrated in vacuo. The title compound was obtained as yellow residue in 94% yield. MS m/e (M+H)+=316.
