Reaction Steps

A mixture of methyl 1-chloro-4-hydroxyisoquinoline-3-carboxylate (1.00 g, 4.21 mmol, from Aldrich), tetramethylstannane (3.01 g, 16.8 mmol), and bis(triphenylphosphine)-palladium(II) chloride (0.295 g, 0.421 mmol) in N,N-dimethylformamide (30 mL) was stirred at 130° C. for 30 minutes. The mixture was cooled to room temperature, quenched with water and then filtered. The filtrate was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated in vacuo. The residue was purified on silica gel chromatography, eluting with 0 to 10% MeOH in dichloromethane, to give the desired product (0.80 g, 88%). LCMS calculated for C12H12NO3 (M+H)+: m/z=218.1; Found: 218.1.
