In the first stage of this investigation, the acylamidines (II-IV) were synthesized by the reaction of (I) with the diethyl acetals of dimethylformamide, dimethylacetamide, and N-methyl-2-pyrrolidone. The reactions proceeded selectively at the amide NH2 group without involving the 3-methylene group, as shown conclusively by their NIfR spectra. For example, the PMR spectrum of the amidine (III) in CDCI3
