Participants

Reaction Steps

In a mixture of acetic acid (5 ml), water (1 ml) and sulfuric acid (0.15 ml) was dissolved 2 g of 1-(2-pyrimidyl)piperazine which was then reacted with 0.86 g of iodine in the presence of 0.38 g of periodic acid at 100° C. for 6 hours with stirring. Chloroform was added to the reaction mixture, followed by washing with sodium hydrogen carbonate and brine. The organic layer thus obtained was dehydrated, filtered and concentrated under vacuum. Purification with column chromatography provided the title compound. 600 mg.
