2-4 dichloropyrimidine  |  2,4-Dichloropyrimidine is a human skin sensitizer. It goes through a highly efficient one-pot, regioselective , double Suzuki coupling reaction that yields diarylated pyrimidines. [2-4 dichloropyrimidine]

Suzuki coupling reaction is frequently used to prepare of a wide range of substituted Pyrimidines. In this study, the Suzuki coupling of 2,4-dichloropyrimidines with aryl and heteroaryl boronic acids was investigated.

A thorough examination of reaction conditions as well as the application of microwave radiation resulted in a highly effective and simple synthetic procedure offering C4-substituted pyrimidines with good yields to exceptional levels.

Short reaction time (15 min) and extremely low catalyst loading (0.5 mol%) are the main advantages of our tetrakis(triphenylphosphine)palladium(0) catalyzed microwave-assisted procedure, which could be used for quick and low-cost regioselective preparation of substituted pyrimidine rings.

2,4-Dichloropyrimidine can be used as a human skin sensitizer. It is subject to a one-pot, regioselective Suzuki coupling reaction that yields diarylated Pyrimidines.

2,4-Dichloropyrimidine was used to synthesize medicinally important 4-aryl-5 pyrimidinyl imidazoles.

Use of sodium sulfonate and tetrabutylammonium bromide as temporary nucleophiles allows for highly regioselective 2,4-dichloropyrimidine amination by weakly nucleophilic amines. This protocol was simple and environmentally friendly and can be applied to many amines as well as activated N-heteroaromatic substrats.

It is revealed that a highly efficient and selective method has been developed for the SNAr animation (2,4-dichloropyrimidine) with oxazolidin-2,one and related weakly Nucleophilic amines.

This was done using sodium sulfinate as a catalyst and tetrabutylammonium bromide as a reactant. This strategy allows for the synthesis and modification of many aminopyrimidines in an efficient and chemoselective way. This strategy was used successfully to amination activated N-heteroaromatic substrates.
