Reaction Steps

A solution of 11.1 g of benzyl tert.butyl hexahydro-2-[3-benzyloxycarbonyl-2(S)-phthalimidopropionyl]-1,3-pyridazinedicarboxylate (diastereomer B) in 220 ml of methanol was hydrogenated over 1.1 g of 10% palladium-on-carbon for 18 hours. The catalyst was removed by filtration and the filtrate was evaporated to give 6.9 g (94%) of tert.butyl hexahydro-2-[3-carboxy-2(S)-phthalimidopropionyl]-3-pyridazinecarboxylate (diastereomer B) in the form of a gum.
