A mixture of 10% Pd/C (100 mg) and benzyl N-(2-oxo-2,3-dihydro-1H-indol-4-yl)glycinate from Step C (320 mg, 1.08 mmol) was stirred vigorously in EtOH (5 mL), EtOAc (5 mL), and AcOH (1 mL) under an atmosphere of hydrogen (ca. 1 atm). After 4 h, the mixture was filtered through a pad of Celite, washing with MeOH, and the filtrate was concentrated to give the title compound. MS: m/z=207 (M+1).
