Versuchsvorschrift

To a solution of 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 (293 mg, 0.38 mmol) in DMF (3.8 mL) was added K2CO3 (371 mg, 2.69 mmol) and 4-mercaptobenzoic acid (207 mg, 1.34 mmol). The reaction mixture was heated in microwave synthesizer at 45° C. for 55 min. After the reaction, water was added, and the mixture was extracted with EtOAc three times. The organic layers were combined and washed with water three times. The combined organic layer was dried over sodium sulfate, filtered off, and concentrated in vacuo. The residue was purified with flash chromatography eluting with EtOAc (containing 20% MeOH and 0.5% ammonia in water)/DCM to provide 150 mg of 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.
