実験手順

To a solution of 4-(3-amino-6-(tetrahydro-2H-pyran-4-yl)pyrazin-2-yl)-2-fluorobenzoic acid (1.55 g, 4.88 mmol) in DMF (16.28 mL) was added HOAt (0.997 g, 7.33 mmol), EDC (1.498 g, 7.82 mmol) DIEA (2.61 m l, 14.65 mmol) and (S)—N-(2-amino-2-(3-chlorophenyl)ethyl)-N-methyl-2-nitrobenzenesulfonamide (2.084 g, 5.13 mmol). The reaction mixture was stirred at room temperature for 3 h, and LCMS indicated the reaction was completed. The reaction mixture was diluted with EtOAc, and the organic was washed by sat.Na2CO3, water and brine, dried over Na2SO4, filtered off, and concentrated. The crude material was purified by flash chromatography eluting with 50% DCM/EtOAc (10% methanol) to provide (S)-4-(3-amino-6-(tetrahydro-2H-pyran-4-yl)pyrazin-2-yl)-N-(1-(3-chlorophenyl)-2-(N-methyl-2-nitrophenylsulfonamido)ethyl)-2-fluorobenzamide (2.68 g, 4.01 mmol, 82%). LCMS: 669.1 (MH+), 0.95 min.
