実験手順

To a round bottomed flask was added tert-butyl(trans-3-aminocyclobutyl)carbamate (1.847 g, 9.92 mmol), 2-(3-chloropyrazin-2-yl)-2-methylpropanoic acid (1.99 g, 9.92 mmol), HATU (4.90 g, 12.89 mmol), and triethylamine (5.52 ml, 39.7 mmol) in DCM (25 ml) to stir at room temperature for 16 h. The reaction mixture was diluted with water and extracted with CH2Cl2. The organic extract was washed with water, saturated NaCl solution, dried over MgSO4, filtered and concentrated in vacuo. The crude product was purified by chromatography through a Redi-Sep pre-packed silica gel column (40 g), eluting with a gradient of 10% to 70% EtOAc in hexane, to provide the title compound (2.73 g, 7.40 mmol, 74.6% yield) as off-white solid.
