632 g) N—((S)-4-Chloro-1-methoxy-2-nitro-9-oxo-6,7,8,9-tetrahydro-5H-benzocyclohepten-7-yl)-acetamide (100 mg, 0.3 mmol), 20% Pd(OH)2/C (30 mg) and Methanol (20 mL) were placed under a blanket of Hydrogen at atmospheric pressure. After 24 h the reaction mixture was filtered and the filtrate concentrated under reduced pressure to yield 105 mg (100%) of N—((S)-2-Amino-1-methoxy-9-oxo-6,7,8,9-tetrahydro-5H-benzocyclohepten-7-yl)-acetamide; hydrochloride.
