Versuchsvorschrift

A round-bottom flask was charged with 7-(benzylthio)-4-(2-chloro-3′-fluoro-5-methoxy-[1,1′-biphenyl]-4-yl)quinazoline (0.490 g, 1.006 mmol), DCM (9.47 ml), DCM (9.47 ml), Acetic Acid (0.355 ml), and Water (0.237 ml) to give a thin suspension. The flask was cooled in an ice-bath for 10 min, then 1,3-dichloro-5,5-dimethylimidazolidine-2,4-dione (0.496 g, 2.52 mmol) was added in one portion, leading to a solution. The reaction was stirred for 15 minutes. 2,3,4,5,6-pentafluorophenol (0.211 ml, 2.012 mmol) was added followed by drop wise addition of triethylamine (0.351 ml, 2.52 mmol). The reaction was stirred for 30 minutes. The reaction was concentrated and purified via column chromatography (RediSep Gold 40 g, gradient elution 0-50% EtOAc:Heptane) to afford perfluorophenyl 4-(2-chloro-3′-fluoro-5-methoxy-[1,1′-biphenyl]-4-yl)quinazoline-7-sulfonate as a light yellow solid. (ESI) 611.2 (M+H)+.
