실험 절차

To a solution of 4-(3-amino-6-((1S,3S,4S)-3-fluoro-4-hydroxycyclohexyl)pyrazin-2-yl)-2-fluorobenzoic acid (156 mg, 0.403 mmol) in DMF (1.28 mL) was added (S)—N-(2-amino-2-(3-bromo-5-fluorophenyl)ethyl)-N-methyl-2-nitrobenzenesulfonamide (180 mg, 0.384 mmol), HOAt (105 mg, 0.768 mmol), DIEA (402 μl, 2.8 mmol), and EDC.HCl (147 mg, 0.768 mmol). The reaction mixture was stirred at room temperature for 15 h, LCMS indicated the product. The mixture was diluted with EtOAc and washed with water and once with saturated Na2CO3 and the organic layer was dried (magnesium sulfate), filtered and concentrated in vacuo providing 4-(3-amino-6-((1S,3S,4S)-3-fluoro-4-hydroxycyclohexyl)pyrazin-2-yl)-N—((S)-1-(3-bromo-5-fluorophenyl)-2-(methylamino)ethyl)-2-fluorobenzamide. The crude product was purified by ISCO column chromatography (0-100% EtOAc in heptane) leading to 4-(3-amino-6-((1S,3S,4S)-3-fluoro-4-hydroxycyclohexyl)pyrazin-2-yl)-N—((S)-1-(3-bromo-5-fluorophenyl)-2-(N-methyl-2-nitrophenylsulfonamido)ethyl)-2-fluorobenzamide (99%).
