Reaction Steps

N-(Diaminophosphinyl)-3-(2-benzoxazolyl)prop enamide (0.25 g) was dissolved in methanol (30 ml) with heating, and 10% Pd--C (wet) (0.05 g) was added. The mixture was hydrogenated at room temaperature under atmospheric pressure for 1 hour. The catalyst was removed by filtration, and the filtrate was concentrated under reduced pressure. Precipitated crystals were collected by filtration to give N-(diaminophosphinyl)-3-(2-benzoxazolyl)propinonamide (0.17 g) as colorless crystals.
