반응 단계
To a solution of 4-methyl-thiazole-2-carboxylic acid ethyl ester (171 mg, 1.0 mmol) in acetonitrile (5 ml) is added NBS (180 mg, 1.0 mmol). The reaction mixture is stirred at rt for 2 hr followed by the addition of a second portion of NBS (180 mg, 1.0 mmol). After stirring at rt for 3 hr, the solvent is removed. The resulting residue is purified by PTLC to give the title compound.
