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.

PKC inhibitors are disclosed. The PKC inhibitors are useful for treating PKC associated diseases, including certain cancers. The PKC inhibitors have improved efficacy at lower dosage amounts to achieve tumor regression, improved potency, PK profile, absorption, gastrointestinal tolerance and kinase selectivity.
