Procedure

A solution of Pd(Amphos)2Cl2 (0.442 g, 0.624 mmol), (4-chloro-2-methoxyphenyl)boronic acid (1.278 g, 6.86 mmol), 1-chloro-N-(pyrimidin-4-yl)isoquinoline-6-sulfonamide (2.000 g, 6.24 mmol), and potassium phosphate (5.29 g, 24.94 mmol) in 30 mL dioxane/12 mL water was heated to 110° C. for 2 hours. LC/MS showed product, so the reaction mixture was allowed to cool to room temperature. The aqueous layer was removed, and the reaction mixture was treated with HCl (4N in dioxane) (6.24 ml, 24.94 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′-chloro-2′,3-dimethoxy-[1,1′-biphenyl]-4-yl)-N-(pyrimidin-4-yl)isoquinoline-6-sulfonamide (0.073 g, 0.137 mmol, 2.197% yield). 1H NMR (MeCN-d3) δ: 8.69 (m, 1H), 8.62 (s, 1H), 8.44-8.52 (m, 1H), 8.21 (d, J=6.4 Hz, 1H), 7.89-7.99 (m, 2H), 7.81 (d, J=9.0 Hz, 1H), 7.42 (m, 1H), 7.32-7.39 (m, 1H), 7.29 (s, 1H), 7.24 (m, 1H), 7.16 (d, 1H), 7.03-7.12 (m, 2H), 3.84-3.88 (m, 3H), 3.64-3.67 (m, 3H); (M+H)+=533.0.
