실험 절차
Trans-N1-(benzo[d]thiazol-2-yl)cyclobutane-1,3-diamine (intermediate 11, 0.058 g, 0.264 mmol) and 2,3-dichloropyrazine (0.035 ml, 0.336 mmol) were suspended in isopropanol (1 mL) in a microwave vial. The mixture was heated at 150° C. for 90 minutes. The mixture was evaporated to dryness under reduced pressure and purified using silica chromatography (hexane to ethyl acetate gradient) to give trans-N1-(benzo[d]thiazol-2-yl)-N3-(3-chloropyrazin-2-yl)cyclobutane-1,3-diamine (0.0594 g, 0.179 mmol, 67.7% yield) as an oil.
