The Synthesis and Chlorination of Some Pyrimidin-4-ols Having 5-Nitrogen Functionality
Harnden, Michael R.,Hurst, Derek T.
, p. 47 - 53 (2007/10/02)
Syntheses of a number of pyrimidin-4-ols having 5-nitrogen functionality are described.Phosphorus oxychloride/diethylaniline chlorination of 6-amino-2-methylthio-5-nitropyrimidin-4-ol gave the corresponding 6-chloro derivative.However, 2-amino-6-methylthi
