A new strategy for a one-pot synthesis of 2-amino-4, 6-diaryl pyrimidines using CsOH/γ-Al2O3 as a heterogeneous, reusable basic catalyst is presented. The developed synthetic protocol for pyrimidines is a one-pot three-component reaction of acetophenone, aromatic aldehydes and guanidine hydrochloride in ethanol. Characterization of the catalyst CsOH/γ-Al2O3 was performed by using FT-IR, XRD, TG-DTA

A flow-based route to imatinib, the API of Gleevec, was developed and the general procedure then used to generate a number of analogues which were screened for biological activity against Abl1. The flow synthesis required minimal manual intervention and was achieved despite the poor solubility of many of the reaction components.

Continuous flow processing was applied for the rapid replacement of an aromatic amino group with a hydride. The approach was applied to a range of aromaticheterocycles, confirming the wide scope and substituent-tolerance of the processes. Flow equipment was utilized and the process optimised to overcome the problematically-unstable intermediates that have restricted yields in previous studies relying

Amino pyrimidines have been synthesized by a one‐pot procedure under environmentally friendly reaction conditions at room temperature. The use of aqueous PEG‐400 circumvents the problems associated with the toxic, hazardous organic solvents and oxidizing agents.
무수탄산칼륨 존재 하에서 2-chloro-N-(4,6-diarylpyrimidin-2-yl)acetamides 25-33를 모르포린과 축합 반응시켜서 2-morpholino-N-(4,6-diarylpyrimidin-2yl)acetamides 34-42 화합물들을 합성하였다. 합성된 화합물들의 녹는점, 원소분석, MS, FT-IR, $^1H$- & $^13}C$-NMR로 화학적인 구조를 규명되었다.
A new series of novel 2-morpholino-N-(4,6-diarylpyrimidin-2-yl)acetamides 34-42 is synthesized by the condensation of 2-chloro-N-(4,6-diarylpyrimidin-2-yl)acetamides 25-33 with morpholine in the presence of anhydrous potassium carbonate. The synthesized compounds have been characterized by melting point, elemental analysis, MS, FT-IR, one-dimensional NMR ($^1H$ & $^13}C$) spectroscopic data.
