실험 절차

O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (474 mg, 1.25 mmol) was added over 30 seconds in portions to a stirred solution of 3-ethoxy-3-oxopropanoic acid (150 mg, 1.13 mmol), N-ethyl-N-isopropylpropan-2-amine (0.394 mL, 2.26 mmol) and 3-(5-(tert-butyl)-1,3,4-oxadiazol-2-yl)-5-(1-ethyl-3-(piperidin-4-yl)-1H-1,2,4-triazol-5-yl)pyrazin-2-amine (450 mg, 1.13 mmol) dissolved in DMF (20 mL) at 50° C. The resulting solution was sampled after 1 min (complete reaction) and immediately allowed to cool to ambient temperature. The reaction mixture was concentrated and diluted with EtOAc (100 mL), and washed sequentially with water (20 mL) and saturated brine (20 mL). The organic layer was dried over MgSO4, filtered and evaporated to afford crude ethyl 3-(4-(5-(5-amino-6-(5-(tert-butyl)-1,3,4-oxadiazol-2-yl)pyrazin-2-yl)-1-ethyl-1H-1,2,4-triazol-3-yl)piperidin-1-yl)-3-oxopropanoate (850 mg).
