Procedure

To a solution of 1-butyl-5-iodo-2-oxo-1,2-dihydropridine-3-carboxylic acid benzylamide (3-067) (78 mg) in DMF (2.0 mL) were added PdCl2(PPh3)2 (15 mg), phenylacetylene (89 mg), CuI (11 mg), and triethylamine (48 mg) at room temperature. After stirred at 90° C. for 18 h, to the reaction mixture were added a saturated aqueous solution of ammonium chloride and ethyl acetate. The organic layer was separated and the aqueous layer was extracted three times with ethyl acetate, and the combined organic layers were washed with water and brine, dried over anhydrous magnesium sulfate, and evaporated under reduced pressure. The obtained crude product was purified by the preparative thin-layer chromatography (toluene/acetone=7/1) to give 1-butyl-2-oxo-5-phenylethynyl-1,2-dihydropridine-3-carboxylic acid benzylamide (3-069) (65 mg, 89%) as an oil.
