tert-Butyl 2-[2-(ethoxycarbothioylamino)-3-pyridyloxy]acetate and tert-butyl 2-(3-thioxopyrido[2,1-c][1,2,4]thiadiazol-8-yloxy)acetate.
Compounds (I), C(14)H(20)N(2)O(4)S, and (II), C(12)H(14)N(2)O(3)S(2), are two minor products of the same reaction. Both structures contain identical ester functionalities in similar orientations. Both independent molecules of (I) contain an ethoxycarbothioylamine moiety, whilst (II) possesses a novel exocyclic thione system fused with a pyridine ring.
