The efficient synthesis of N-substituted-2-propynamides was accomplished by three methods; the reaction of amines with either the N-hydroxysuccinimide ester or mixed anhydride of propiolic acid, or by the interaction of lithiotrimethylsilylacetylene with isocyanates followed by desilation with fluoride.
