Reaction of 1‐(5‐acetyl‐4‐methylthiazol–2‐yl)–3‐phenylthiourea 2 with hydrazonoyl chlorides ( 3a , 3b , 3c , 3d , 3e , 3f ) and 9 yielded the corresponding (thiazolyl)imino–1,3,4‐thiadiazole derivatives ( 6a , 6b , 6c , 6d , 6e , 6f ) and 12 , respectively. Reaction of 2 with ethyl chloroacetate 13 gave (thiazolyl)imino‐1,3‐thiazolidin‐4‐one derivative 15 , which upon condensation with aromatic aldehyde derivatives yielded the 5‐benzylidene derivatives ( 16a , 16b ). In addition, treatment of 2 with 3‐chloropenta‐2,4‐dione 17 afforded the corresponding (thiazolyl)imino‐1,3‐thiazole derivative 19 . The newly synthesized compounds were confirmed from their elemental analyses and spectral data.
