  Selective addition of amines to 5-trifluoromethyl-2,4-dichloropyrimidine induced by Lewis acids

  摘要：

  A variety of 2,4-diamino-pyrimidine systems can be prepared from the corresponding 2,4-dichloropyrimidine by sequential addition of two amines, the first adding selectively to the 4-position. In contrast it was found that 2,4-dichloro-5-trifluoromethyl-pyrimidine yields a 1:1 mixture of the two possible isomers. Lewis acids were employed to increase the ratio of isomers to >10:1 in favor of the 2-addition product. Optimization of the effect of Lewis acid additives on this and other dichloropyrimidine systems will be discussed. (C) 2013 Elsevier Ltd. All rights reserved.

  The present invention relates to a method of making a compound of the formula (I),wherein X1, X2 and R3-R4 are as defined herein. The method includes reacting a compound of the formula (II) with an amine of formula (III) (HNR3R4) in the presence of a Lewis Acid and a non-nucleophilic base. The 2,4-diamino pyrimidine moiety is a common component in a variety of biologically active drug-like molecules and pyrimidine derivatives have been found to be useful in the 10 treatment of abnormal cell growth, such as cancer, in mammals.
