Reaction Steps

A solution of 1.09 g (2.60 mmol) 1-(t-butylacetamido)-3-azido-5,7-diphenylhexahydroazepin-2-one in 30 mL ethanol and 15 mL methylene chloride was hydrogenated at 42 psi in the presence of 0.40 g 10% palladium-on-carbon for 36 hours. The reaction showed Rf 0.30/0.15 iodoplatinate positive, in 30% methanol in ethyl acetate. It was filtered through Celite with ethanol and methylene chloride, evaporated, and chromatographed on silica gel using 30% methanol in ethyl acetate as eluant to afford 300 mg (29%) of the less polar diastereomer as an oil and 420 mg (41%) of the more polar diastereomer as an oil.
