Reaction Steps

Palladium acetate (0.28 g) was added to a heated mixture of trifluoro-methanesulfonic acid 1-amino-3-methylisoquinolin-6-yl ester (1.9 g), zinc cyanide (0.74 g) and triphenylphosphine (0.33 g) in 24 mL of N-methyl-pyrrolidone at 190° C. (exothermic!). Stirring was continued at 190° C. for 2 h After cooling to room temperature, ethyl acetate was added and the organic mixture washed with 2N aqueous ammonia, water and brine and dried (magnesium sulfate). Filtration and concentration afforded a brownish oil, which was purified by silica chromatography (dichloromethane/methanol=98/2) to give 0.68 g of the title compound. ESI-MS: 184 (MH+).
