Reaction Conditions

Reaction Steps

1.22 mL 2-oxo-propionic acid, 0.26 g palladium acetate and 3.20 mL triethylamine were added to a solution of 1.00 g 2-bromo-pyridin-3-yl amine and 1.21 g triphenyl-phosphine in 10 mL N,N-dimethylformamide. The reaction mixture was stirred for 4 hours at 100° C. After removal of the solvent under reduced pressure, the residue was purified by column chromatography on silica gel with dichloromethane/methanol as eluent. Yield: 260 mg MS(ES+): m/e=163.
