Procedure

A microwave vial charged with di-tert-butyl(2′,4′,6′-triisopropyl-3,4,5,6-tetramethyl-[1,1′-biphenyl]-2-yl)phosphine (0.017 g, 0.035 mmol), 4-fluorophenol (0.039 g, 0.351 mmol), 1-(4-chloro-2-methoxyphenyl)-N-(pyrimidin-4-yl)isoquinoline-6-sulfonamide (0.075 g, 0.176 mmol), potassium phosphate (0.149 g, 0.703 mmol), 1.5 mL dioxane was heated to 135° C. in the microwave for 30 minutes. LC/MS showed mostly product, so the reaction mixture was filtered through a 0.45 μm syringe filter and was treated with HCl (4N in dioxane) (0.176 ml, 0.703 mmol). After stirring for 10 minutes, the reaction mixture was concentrated. 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 1-(4-(4-fluorophenoxy)-2-methoxyphenyl)-N-(pyrimidin-4-yl)isoquinoline-6-sulfonamide (0.020 g, 0.040 mmol, 22.65% yield). 1H NMR (MeCN-d3) δ: 8.68 (d, J=5.7 Hz, 1H), 8.62 (s, 1H), 8.48 (s, 1H), 8.23 (d, J=8.5 Hz, 1H), 7.88-7.98 (m, 2H), 7.83 (d, J=9.0 Hz, 1H), 7.25-7.33 (m, 1H), 7.13-7.21 (m, 4H), 7.08 (d, J=5.4 Hz, 1H), 6.83 (s, 1H), 6.62-6.69 (m, 1H), 3.60 (s, 3H); (M+H)+=503.0.
