A NEWLY SYNTHESIS AND IDENTIFICATION OF 5-NITRO-2,4,6- TRIPHENYL HEXAHYDRO PYRIMIDINE DERIVATIVES STRUCTURES

Abstract

The Mannich reaction was used to synthesise new hexahydro pyrimidine derivatives with good to excellent yields of eleven derivatives. The reaction was based on the condensation of three major components, nitromethane, ammonium acetate, and mono- or di-substituted benzaldehyde compounds in the ratio 1:2:3, which were mixed with n-butanol as a solvent system. All products were characterized using the fundamental techniques of FT-IR, 1H-NMR, and mass spectroscopy
