Reaction Steps
A suspension of 2-(2,3-dihydro-1H-imidazo[1,2-b]pyrazol-7-yl)ethylamine (155 mg) in ethyl formate (3 ml) was refluxed for 4.5 hours. After evaporation of the solvent in vacuo, the residue was triturated with ethyl acetate and dried in vacuo to give 2-(2,3-dihydro-1H-imidazo[1,2-b]pyrazol-7-yl)ethylformamide (165 mg) as a solid.
