A solution of 13.7 grams (31.6 mmol) N-(t-Butyl)-2-oxo-3-azido-5-(2-methylphenyl)-7-phenyl-2,3,4,5,6,7-hexahydroazepin-1-yl ethanoic amide in 120 mL ethanol and 60 mL methylene chloride was hydrogenated at 42 p.s.i. in the presence of 3.9 grams 10% palladium-on-carbon for 36 hours. It was then filtered through celite with ethanol and methylene chloride, evaporated, and chromatographed on silica gel using 15% and 30% methanol in ethyl acetate as eluent to afford 12.2 grams (95%) of a foam.
