A GREENER CHEMISTRY APPROACH FOR SYNTHESIS OF 4-(4-HYDROXYPHENYL)-6-METHYL-2-OXO-1,2,3,4 TETRAHYDROPYRIMIDINE-5-CARBOXYLIC ACID ETHYL ESTERAbstract
The objective of present research work is to provide green technique for synthesis of 4-(4-Hydroxyphenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid ethyl ester. Pyrimidine derivatives are well known in the pharmaceutical industry and exhibit to possess a broad spectrum of biological activities. Highly efficient and simple methods complying with principle of Green chemistry have been described in this manuscript for the synthesis with competent yields. As part of current studies, we here in report economical practical techniques like- microwave synthesis, mortal-pastel method (mechanochemistry) and by application of green solvents. On completion of reaction the products were characterized by IR, NMR and Mass Spectra. These methods are more convenient and reactions can be carried out in higher yield (80-96%), shorter reaction time (3-30 min) and milder conditions, without generation of pollution and safer to analyst.
