Procedure

A mixture of 2-bromo-benzoic acid ethyl ester (458 mg, 2.0 mmol), 7-aminoisoquinoline (144 mg, 1.0 mmol), Pd(OAc)2 (11 mg), BINAP (30 mg) and K2CO3 (414 mg) in 1 mL of toluene was stirred in a sealed tube for 16 h at 105° C. The reaction was cooled to RT, diluted with 20 mL of CH2Cl2, filtered through Celite®, concentrated, and purified by flash column chromatography to obtain the titled compound as an oil. MS (ES+): 293.3 (M+H)+. Calc'd for C18H16N2O2-292.
