Procedure

N—(N-(3-chloro-4-fluorophenyl)-7-methoxy-3-(pyridin-3-yl)isoquinolin-1-amine was prepared using Method J. A mixture of 1-chloro-7-methoxy-3-(pyridin-3-yl)isoquinoline (40 mg, 0.17 mmol, 1.0 eq.), 3-chloro-4-fluoro aniline (30 mg, 0.21 mmol, 1.2 eq.), Pd2(dba)3 (10 mg, 0.011 mmol, 0.06 eq.), Xantphos (15 mg, 0.026 mmol, 0.15 eq.), cesium carbonate (167 mg, 0.52 mmol, 3.0 eq.) was suspended in the mixed solvent of 1,4-dioxane (4 mL) and water (1 mL). The resulting mixture was stirred at 120° C. for 30 min under the microwave conditions. After cooling, the resulting mixture was partitioned between water and ethyl acetate. The combined organic layers were washed with water and brine, dried over anhydrous sodium sulfate. After filtration and evaporation, the residue was purified by prep-HPLC to afford 3 mg of xli-a as a yellow solid (yield 5.2%). LCMS m/z=380.1 (M+1) (Method B). 1H NMR (400 MHz, DMSO-d6): δ 9.35 (s, 1H), 9.30 (d, J=2.0 Hz, 1H), 8.57 (dd, J=4.7, 1.5 Hz, 1H), 8.41 (td, J=8.0, 1.8 Hz, 1H), 8.30 (dd, J=6.9, 2.6 Hz, 1H), 7.94-7.87 (m, 4H), 7.43-7.49 (m, 3H), 3.99 (s, 3H).
