SYNTHESIS AND REACTIVITIES OF 5-HYDROXYPYRIMIDINE 1-OXIDES IN ELECTROPHILIC SUBSTITUTION
1-Oxides of a series of 5-hydroxypyrimidine derivatives were synthesized, and their reactivities in electrophilic-substitution reactions (aminomethylation) as compared with 3-hydroxypyridine 1-oxides were investigated.It is shown that the activity of the
