실험 절차

A suspension of 1-benzyl-1H-pyrazol-5-amine (1.7 g), 4-isopropylphenylboric acid (2.0 g), copper acetate (1.8 g), pyridine (4.0 mL) and molecular sieves 4A (4 g) in tetrahydrofuran (50 mL) was stirred for 15 hr. The reaction mixture was diluted with ethyl acetate, the insoluble material was filtered off through celite, and the filtrate was concentrated. The residue was purified by silica gel column chromatography to give the title compound as a pale-yellow amorphous solid (0.80 g, 26%).
