Potassium Iodide → HCID 54104364, compound

Participants

Reaction Steps

A mixture of 5.43 g of 2-amino-4-[5-(4-chlorobutyl)-2-thienyl]thiazole, 4.0 g of 4-phenylpiperazine, 3.2 g of potassium carbonate, 0.1 g of potassium iodide and 50 ml of dimethylformamide is stirred at 70°-80° C. for 15 hours. The resultant mixture is poured into water and extracted with water. The extract is washed with water and dried over magnesium sulfate. After the solvent is distilled off under reduced pressure, the residue is recrystallized from ethanol to give 2-amino-4-[5-(4-(4-phenyl-1-piperazinyl) butyl)-2-thienyl]thiazole, melting at 165°-167° C.
