실험 절차

To a solution of 5-Chloro-4-(oxetan-3-yloxy)-pyridine-2-carboxylic acid (Example 23a, 35 mg, 152 μmol) in DMF (1 mL) was added HATU (58 mg, 152 μmol) and DIEA (66.6 μL, 381 μmol). The reaction mixture was then stirred at room temperature for 30 min, followed by addition of (S)-2-amino-N,3,3-trimethylbutanamide (CAN 89226-12-0, 22 mg, 152 μmol). The reaction mixture was stirred for 3 h. The crude reaction mixture was directly purified by preparative HPLC to deliver the desired compound (17.5 mg, 32%) as a yellow oil. MS (ESI, m/z): 356.5 (M+H+).
