IR and 1H NMR Spectral Studies of some 2-Amino-4-Isopropyl-6-Methoxy-N-Phenylpyrimidine-5-Carboxamides: Assessment of Substituent Effects

Full Text PDF

Abstract:

A series of 2-Amino-4-isopropyl-6-methoxy-N-phenylpyrimidine-5-carboxamide compounds have been synthesized from various substituted dithioacetal and guanidine. The purities of these compounds were checked by their physical constants, UV, IR, NMR and MASS spectral data. The IR and 1HNMR spectral data of these compounds have been correlated with Hammett sigma constants, F and R parameters using single and multi-linear regression analysis. From the results of statistical analysis, the effects of substituents on the spectral group frequencies have been discussed.
