"Pyrimidines. XXI. Synthesis of 4(6)-substituted 20 fluoropyrimidines"
Riga, Kbinlya Geterotsiklicheskikb Soyedineniyg No 91 1972, pp 1281-1284
Abstracti The synthesis of 2-ifluoropyrimidine (I) and its 4(6)-substituted
derivatives (II-X) Is described, and a study is made of the1w reactivity and
the effect of the nature of the substituents on the mobility of the fluorine
atom in nucleophilic substitution.. The 4(6)-substituted derivatives are
obtained by the action of cesiuz fluoride on the corresponding 2-chloropyrimi-
dines in aprotonic bipolar solvents. Spectral and nuclear magnetic resonance
data are prenented which confirm the picture of the fluoropyrimidines obtained.
The experimental procedures and yields are given for the reaction of chloro-
pyrimidines with cesium fluoride and the aeparation oe 2-fluoropyrimidinat
