Reaction Steps
To a stirred solution of (3S-trans)-3-[(2,6-dimethoxybenzoyl)amino]-4-methyl-1-[(phenylmethyl)oxy]-2-azetidinone (0.848 g) in absolute ethanol (20 ml) under nitrogen is added 1,4-cyclohexadiene (8 ml) and freshly prepared palladium black (approximately 0.85 g). After one hour the reaction mixture is filtered and evaporated to a solid (0.605 g).
