Benzylamine → 5-Iodo-N-(phenylmethyl)imidazo[2,1-b]-1,3,4-thiadiazol-2-amine

Participants

Reaction Steps

5-Iodo-2-methanesulfinyl-imidazo[2,1-b][1,3,4]thiadiazole (500.00 mg; 1.60 mmol; 1.00 eq.) was dissolved in dichloromethane (1.60 ml) and benzylamine (622.18 μl; 4.79 mmol; 3.00 eq.) was added. Then, the reaction was refluxed overnight. The reaction was concentrated in vacuo. Then, 5 ml of isopropanol were added and the suspended solution was heated under reflux for 15 min. The mixture was allowed to cool to room temperature and then cooled to 0° C. After 15 min at 0° C., the solid was filtered and washed with isopropanol to give a white solid. The solid was dried at 60° C. for 1 h to give 460.2 mg of the desired product.
