Participants

Reaction Steps

A microwave vial was charged with 1-chloro-N-(2,4-dimethoxybenzyl)-4-fluoro-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (Intermediate PPP; 0.075 g, 0.152 mmol), (2-hydroxyphenyl)boronic acid (0.031 g, 0.228 mmol), tetrakis(triphenylphosphine)palladium(0) (0.018 g, 0.015 mmol), and potassium carbonate (0.105 g, 0.759 mmol). Dioxane (0.759 mL) and Water (0.253 mL) were added; the vial was flushed with argon and sealed, and microwaved at 100° C. for 30 minutes. The reaction was diluted with ethyl acetate and washed with water. The aqueous layer was extracted with ethyl acetate, and the combined organic layers were dried with sodium sulfate, filtered, and concentrated. The material was purified via column chromatography (RediSep Gold 12 g, gradient elution 0-100% EtOAc:Heptane) to afford N-(2,4-dimethoxybenzyl)-4-fluoro-1-(2-hydroxyphenyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide. (ESI) 522.2 (M+H)+.
