실험 절차

A mixture of 10% Pd/C (900 mg) and (S)-5-amino-6-nitro-1,3-dihydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one from Step A (3.00 g, 10.1 mmol) was stirred vigorously in MeOH (500 mL) and EtOAc (700 mL) under an atmosphere of hydrogen (ca. 1 atm). After 18 h, the mixture was filtered through a pad of Celite, washing with MeOH, and the filtrate was concentrated in vacuo to give the title compound. MS: m/z=267 (M+1).
