The antithrombic (no data) title compds. [I;R1 = (substituted) aryl; R2 = H, aliph. group, substituted aryl; R3 = (substituted) naphthyl, furyl, thienyl, Ph, or phenalkyl were prepd. by reaction of II and III. Thus, 16.7 g 2-amino-5-(2-furyl)-1,3,4-thiadiazole reacted with 20 g bromoaceto phenone in 100 ml DMF to give 21.2 g I (R1 = Ph; R2 = H; R3 = 2-furyl).
