2-Amino-4,5-diphenylthiazole → HCID 15232782, compound

Participants

Reaction Steps

3.12 g of 2-amino-4,5-diphenylthiazole and 2.44 g of 4-trifluoromethylbenzenesulfonyl chloride were stirred in pyridine at room temperature for 4.5 hours. Then the reaction mixture was poured into ice-water and the crystals thus precipitated were recovered by filtration and recrystallized from isopropyl ether/ethyl acetate to give 0.55 g of 2-(4-trifluoromethylbenzenesulfonyl)amino-4,5-diphenylthiazole. The melting point of this product was from 248° to 249° C.
