Procedure

To a mixture of 1-(benzyloxy)-7-bromo-3-chloroisoquinoline (1.00 g, 2.86 mmol, 1.0 eq), 3-methoxyphenylboronic acid (435 mg, 2.86 mmol, 1.0 eq), K2CO3 (2.13 g, 15.4 mmol, 5.4 eq) in dioxane (10 mL) and H2O (5 mL) was added Pd(PPh3)2Cl2 (100 mg, 0.15 mmol, 0.05 eq) under N2 atmosphere. The resulting mixture was stirred at 110° C. under N2 atmosphere overnight. The solvent was removed in vacuo and the residue was purified with chromatography on silica gel (hexane/ethyl acetate 250:1) to give 550 mg of lxvi-a as white solid (yield 37%). LCMS m/z=376.0 (M+1) (Method B) (retention time=2.43 min).
