Reaction Steps

A solution of 1.0 g. of 2-amino-1-[5-amino-1-(phenyl-methyl)-1H-imidazol-4-yl]ethanone dihydrochloride in 100 ml. of 70:20:10 methanol:water:acetic acid is hydrogenated over 0.52 g. of 20% palladium-on-carbon at 50 p.s.i. until hydrogen uptake ceases. The catalyst is removed by filtration and the filtrate is evaporated at reduced pressure to give 2-amino-1-(5-amino-1H-imidazol-4-yl)ethanone dihydrochloride; m.p. above 250° dec.
