참여 물질

반응 단계

A solution of 2-(3,4-dichlorophenyl)-3-hydroxy-4-methylcarbonylthiophene (25 mg, 0.087 mmol) and quinoxaline-6-carboxylic acid hydrazide (25 mg, 0.087 mmol) in dimethylsulfoxide (0.5 mL) was stirred at 100° C. for 12 hours and the reaction mixture was concentrated under the reduced pressure. To the residue was added chloroform and the precipitated solid was collected by filtration and dried by means of a vacuum pump to give the desired product as a pale yellow solid (yield 10%).
