실험 절차

Phenyl N-(5,6-dimethyl-2-methoxypyrazin-3-yl)thiocarbamate (200 mg, 0.69 mmol) and 1-(3,5-dimethoxyphenyl)piperazine (154 mg, 0.69 mmol) were dissolved in anhydrous tetrahydrofuran (25 ml) and thereto DBU (105 mg, 0.69 mmol) was added. The mixture was stirred at room temperature for 2 hours, concentrated under the reduced pressure to remove the solvent and purified by column chromatography to obtain the titled compound.
