Abstract
Amino-2-dimethylamino-5-nitrosopyrimidin-4(3H)-one (1) was condensed w ith a series of dimethylphenacylsulfonium bromides (2) in pyridine to yield methylamino-3,4,5,6-tetrahydropteridine-4,6-diones (xanthopterin derivatives) (5) which were reduced to yield the corresponding 7,8-di hydro derivatives (6).
