Participants

Reaction Steps

To a solution of 2-(4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidin-3-yl)ethylamine dihydrochloride (2.36 g) and ethyl formate (40 g) in methanol (20 ml) was added 28% sodium methoxide solution in methanol (4.0 g), and the mixture was stirred under reflux for 16 hours. The insoluble materials were filtered off using Celite, and the filtrate was concentrated in vacuo. The residue was triturated with acetonitrile and dried in vacuo to give N-[2-(4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidin-3-yl)ethyl]formamide (1.2 g) as a solid.
