The site-selectivity in the modified Reissert-Henze reaction of 5-substituted and 4,5-disubstituted pyrimidine 1-oxides with trimethylsilyl cyanide was examined.The reaction of 5-substituted 4-methoxypyrimidine 1-oxides with trimethylsilyl cyanide gave exclusively 2-pyrimidinecarbonitriles in good yields without exception.On the other hand, the other 5-substituted and 4,5-disubstituted pyrimidine 1-oxides gave mainly 6-pyrimidinecarbonitriles.Keywords--site-selectivity; pyrimidine N-oxide; trimethylsilyl cyanide; Reissert-Henze reasction; pyrimidinecarbonitrile
