Participants

Reaction Steps

To 17.4 of ethyleneurea is added with shaking 36 g of piperidinosulfonyl chloride (b.p. 130°/11 mm) and the mixture kept under nitrogen at 100° for 3 hrs. The mixture is cooled and the gummy material treated with methanol-isopropanol (1:1) to give a granular product of 1-piperidinosulfonyl-2-oxo-tetrahydroimidazole which melts at 201° on recrystallization from methanol.
