Yield:17616-04-5 93 %Chromat.

Reaction Conditions:

with C16H12ClN3OPdS;potassium hydroxide in dimethyl sulfoxide at 110; for 10 h;

Steps:

2.3. Catalytic arylation of nitrogen-containing heterocycles with aryl halides

General procedure: Arylhalide (1.0 mM), nitrogen-containing heterocycle (1.2 mM), KOH (2 mM), and the catalyst (0.75 M%) were stirred in dimethyl sulfoxide (DMSO) (4 mL) at 110 °C for 10 h. After completion of the reaction, the mixture was cooled to room temperature, diluted with ethyl acetate (10 mL) and filtered. The filtrate was concentrated and the residue was purified by column chromatography on silica gel using hexane/ethyl acetate(70 : 30) as eluent to afford the desired product. The products have been characterized by 1H NMR spectroscopy.
