## Abstract A general method is described for the synthesis of 1โ€arylโ€2โ€alkylโ€1,4,5,6โ€tetrahydropyrimidines 1, by cyclization of __N__โ€acylโ€__N__โ€ฒโ€aryltrimethylenediamines 2 with trimethylsilyl polyphosphate. Precursors 2 were obtained by aminolysis of the corresponding __N__โ€(3โ€bromopropyl)amides

Further proof of structure of 2-oxo-4-(3,4-diethoxyphenyl)-5-carbethoxy-6-trifluoromethyl-l,2,3,4-tetrahydropyrimidine was obtained by comparison of the infrared spectrum\* of the compound with that of the 6-methyl analog. The spectra are identical except that a strong band for the C-F bond was foun
