Vishvanath Dhamba Patil*, Prathamesh Vidyadhar Gidh, Amruta Mohan Salve

An efficient method for the synthesis of 4,6-diarylpyrimidin-2(1H)-ones or thiones by using SiO2.CAA. The condensation of acetophenone, aldehydes and urea or thiourea in the presence of silica supported catalyst was employed to synthesize a variety of pyrimidinones or thiones in excellent yields. The remarkable feature of this synthetic pathway is simple workup, shorter reaction times, high yields
