反応手順
A suspension of EXAMPLE 198B (800 mg), N,N-dimethylprop-2-yn-1-amine (373 mg), copper(I) iodide (57 mg), tetrakis(triphenylphosphine)palladium(O) (259 mg), triethylamine (757 mg) and tert-butyl ammonium iodide (829 mg) in anhydrous N,N-dimethylformamide (5 mL) was heated at 100° C. for 5 hours. The reaction mixture was cooled to room temperature and diluted with ethyl acetate. The organic phase was washed with water, brine, dried over anhydrous sodium sulfate, filtered, and concentrated. The crude material was purified by flash column purification with 0-3% methanol/dichloromethane to afford the title compound.
