Reaction Steps

To a solution of 1-methoxycarbonylmethyl-2,3-dihydro-1H-imidazo[1,2-b]pyrazole (27 g) in ethanol (135 ml) was added 28% ammonium solution (100 ml). The mixture was stirred overnight at room temperature. The insoluble material was filtered off and the filtrate was evaporated to precipitate the crystals. The crystals were collected by filtration to give 1-carbamoylmethyl-2,3-dihydro-1H-imidazo[1,2-b]pyrazole (6 g).
