“…"2-Amino-3-cyano-4-methylfuran 1, 2-amino-3-cyano-pyrans 2, 1-Phenyl-3-thiomethyl-5-aminopyrazole-4-carbonitrile 3" were selected as our primary starting material for this synthesis and were prepared by methods taken from the literature [21][22][23], the reactivity of the cyanoacetic acid hydrazone has been already reported by the present authors [24,28]. Compound 1, 2 and 3 reacted with excess of ethyl orthoester to yield iminoethers 4, 5 and 6 (Scheme 2), which were known to react with compounds containing -NH 2 moiety such as hydrazides [4,[25][26][27][28][29].…”
