Abstract:	Urea or thiourea, ethyl acetoacetate, and substituted aromatic aldehydes were combined in a one-pot Biginelli coupling reaction to create a few 1, 2, 3, 4-tetrahydro pyrimidine-5-carboxylate derivatives without any unsafe organic solvent. The catalyst used for this reaction was nickel nitrate hexahydrate [Ni(NO3)2.6(H2O)]. The elemental analyses, mass spectral data, 1H-NMR, 13C-NMR, UV, and IR were used to characterize the separated pure products.
