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

## Abstract magnified image In the context of our highβthroughput organic synthesis program, we have studied the reactivity of special Ξ²βketo esters toward the Biginelli reaction. We have found that a diethylβ3βoxoglutarate reacts with one molecule of urea and one molecule of aldehyde under solven
