Reaktionsschritte

A microwave vial charged with Pd(Amphos)2Cl2 (0.012 g, 0.018 mmol), 4,4,5,5-tetramethyl-2-(5-methylfuran-2-yl)-1,3,2-dioxaborolane (0.073 g, 0.351 mmol), 1-(4-chloro-2-methoxyphenyl)-N-(pyrimidin-4-yl)isoquinoline-6-sulfonamide (From Example 160; 0.075 g, 0.176 mmol), potassium phosphate (0.149 g, 0.703 mmol), 1.5 mL dioxane and 0.25 mL water was heated to 150° C. in the microwave for 30 minutes. LC/MS showed mostly product. The aqueous layer was removed, and the reaction mixture was treated with HCl (4N in dioxane). Purification of the crude residue by reverse phase column chromatography [RediSep Gold C18, 10-100% (0.1% NH4OH in MeOH)/(0.1% NH4OH in water)] gave the titled compound.
