AbstractA series of 2,5,6‐trisubstituted imidazo[2,1‐b][1,3,4]thiadiazoles via Mannich reaction of imidazo[2,1‐b][1,3,4]thiadiazoles with morpholine and formaldehyde were synthesized. Structures of all the newly synthesized compounds are well supported by spectral data such as IR, NMR, Mass, and Elemental analysis. Compound 3a has been confirmed by X‐ray diffraction studies. J.
