실험 절차

6-Ethoxy-benzothiazol-2-ylamine (39 mg, 0.20 mmol) and 2-phenyl-butyric acid (33 mg, 0.20 mmol) were dissolved in N,N-dimethylformamide (1 mL) containing triethylamine (84.1 μL, 0.600 mmol). O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (84 mg, 0.22 mmol) was added and the solution was allowed to stir for 16 hours. The crude product was purified by reverse-phase preparative liquid chromatography (17 mg, 0.050 mmol, 25%). ESI-MS m/z calc. 340.1, found 340.9 (M+1)+ Retention time 3.55 minutes.
