実験手順

A degassed solution of phenylacetylene (3.9 ml, 35 mmol) and Et3N (36 mL) in DMF (13.5 mL) was added to N-[4-iodo-3-(trifluoromethyl)-1H-pyrazol-5-yl]acetamide (4.5 g, 14 mmol), CuI (530 mg, 2.8 mmol) and PdCl2(PPh3)2 (980 mg, 1.4 mmol) under an atmosphere of N2. The reaction was then heated to 85° C. for 3.5 h. The reaction mixture was concentrated in vacuo and the residue was purified by column chromatography (silica gel, ethyl acetate/isohexane 1:9 to 1:0) yielding the title compound as a brown oil (3 g) which was used in the subsequent step.
