Procedure

A mixture of 7-bromo-4-hydroxy-isoquinoline-3-carboxylic acid methyl ester (141.0 mg, 0.50 mmol), xantphos (28.9 mg, 0.05 mmol, Strem), Pd2(dba)3 (22.9 mg, 0.03 mmol, Sigma-Aldrich), Cs2CO3 (488.7 mg, 1.5 mmol) and aniline (0.1 mL, 1 mmol) in DMF (5 mL) was stirred at 135° C. for 16 hours under a nitrogen atmosphere. After cooling to room temperature, the mixture was diluted with CH2Cl2 (50 mL) and H2O (50 mL). The layers were separated and the aqueous layer was extracted twice with CH2Cl2. The combined organic layers were dried over MgSO4, concentrated, and purified by flash chromatography (0-30% MeOH/CH2Cl2) to give the title compound in 62.4 mg. MS: (−) m/z 293.04 (M−1).
