실험 절차

A mixture of 1.36 mmol 2-chloro-6-ethoxy-benzothiazole (CA=[79071-17-3]), 3.00 mmol of piperazine and 3.00 mmol of triethylamine in 5 ml of tetrahydrofuran in a sealed tube was heated at 160° C. for 5 min under microwave irradiation. The reaction mixture was concentrated, and the residue was purified by chromatography (SiO2, methanol/dichloromethane) to yield the title compound as a white solid.
