Versuchsvorschrift

A vial containing a suspension of Cs2CO3 (0.292 g, 0.897 mmol), (4-fluoro-2-hydroxyphenyl)boronic acid (0.045 g, 0.292 mmol) and 1-chloro-N-(4-methoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (Intermediate JJJ; 0.1 g, 0.224 mmol) in DME (2.5 ml) and water (0.375 ml) was degassed with nitrogen and tetrakis(triphenylphosphine)palladium (0.026 g, 0.022 mmol) was added. The vial was sealed and heated under microwave irradiation at 125° C. for 30 min. The aqueous layer was discarded using a pipette and the organic layer was concentrated and purified by silica gel chromatography (25 g column, eluting with Hex:EtOAc (0 to 50%)). Pure fractions were combined and concentrated to obtain 1-(4-fluoro-2-hydroxyphenyl)-N-(4-methoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (0.108 g, 0.207 mmol, 92% yield) as light yellow solid.
