Procedure

A stirred solution of 2-(1H-indazol-5-ylamino)-succinic acid 4-tert-butyl ester 1-ethyl ester (123.6 mg, 0.37 mmol) in methylene chloride (2 mL) and trifluoroacetic acid (0.5 mL) was stirred at room temperature overnight. The reaction mixture was then diluted with ethyl acetate and washed with saturated ammonium chloride solution, water and brine. The organic layer was dried and concentrated to give a dark green oil: LC/MS: tR=0.643 min, 278.19 (MH)+.
