A protocol for the synthesis of hindered 4-aryl 2-aminopyrimidines from β–keto esters is described. The process employs trifluoroethanol as an essential additive to promote the guanidine condensation reaction, enabling the synthesis of 25 aryl- and heteroaryl substituted aminopyrimidines in good yields and high purities with no column chromatography. The conditions described herein are readily scalable
描述了由β-酮酸酯合成受阻4-芳基2-氨基嘧啶的方法。该方法采用三氟乙醇作为促进胍缩合反应的必要添加剂,无需柱色谱法即可以高收率和高纯度合成25个芳基和杂芳基取代的氨基嘧啶。本文所述的条件易于扩展,并且已用于临床A 2a / A 2b R拮抗剂AB928的大规模合成。

2-amino-5-bromo-6-phenyl-4(3H)-pyrimidinone. An analogue study incorporating a series of 2-amino-5-substituted-6-arylpyrimidinones revealed that the most potent interferon inducers were mono- and difluorophenyl analogues. These same analogues were also potent antiviral agents against Semliki Forest virus and herpes simplex type 1. In addition the monomethoxyphenyl analogues were potent antiviral agents but weak interferon
