실험 절차

Bromine (6 mmol) was added dropwise to a solution of 2-methyl-4-(4-nitrophenyl)-1,3-thiazole (5 mmol) in chloroform (20 mL) and the solution refluxed for 4 h. The solvent was evaporated and the product purified by crystallization from ether to afford the title compound (60%). ESMS [M+H]+: 300.2
