HCID 226110652-(3'-Nitrophenyl)-4[(3'-methoxy)phenyl]thiazole

Procedure

A mixture of 3-nitrobenzenethioamide (2.73 g, 15 mmol) and 3-methoxy-α-[bromoacetophenone (3.43 g, 15 mmol) in EtOH (30 mL) is heated under reflux for 18 h. It is cooled and filtered to give 4 g of 2-(3′-nitrophenyl)-4[(3′-methoxy)phenyl]thiazole as a yellow solid, mp. 122-123° C.
