Reaction Steps
A suspension of 1-(4-triphenylmethyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidin-3-yl)methylamine (8.4 g) in ethyl formate (30 ml) was stirred at 50° C. for 16 hours. After evaporation of the solvent in vacuo, the residue was triturated with ethyl acetate and dried in vacuo to give N-[(4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidin-3-yl)methyl]formamide (3.0 g) as a solid.
