実験手順

To a solution of 4-(3-amino-6-(tetrahydro-2H-pyran-4-yl)pyrazin-2-yl)-2-fluorobenzoic acid (35 mg, 0.110 mmol) in DMF (368 μl) was added (S)-tert-butyl (2-amino-2-(3-bromo-5-fluorophenyl)ethyl)carbamate (40.8 mg, 0.110 mmol), aza-HOBt (22.52 mg, 0.165 mmol). EDC (31.7 mg, 0.165 mmol), and DIEA (57.8 μl, 0.331 mmol). The reaction mixture was stirred at room temperature for 3 h, and then partitioned between EtOAc and water. The organic was washed by NaHCO3, water and brine, dried over Na2SO4 and concentrated. The crude (S)-tert-butyl (2-(4-(3-amino-6-(tetrahydro-2H-pyran-4-yl)pyrazin-2-yl)-2-fluorobenzamido)-2-(3-bromo-5-fluorophenyl)ethyl)carbamate was used in next step reaction without further purification. LCMS (m/z): 632.1/634.1 (MH+), 0.97 min.
