Versuchsvorschrift

To a solution of (1-benzyl-4-methyl-1H-pyrazol-3-yl)methanol (compound 268.2, 3 g, 14.8 mmol) in dichloromethane (100 mL) was added PDC (11.3 g, 30.1 mmol), molecular sieves (3 g) and NaOAc (300 mg) were added to the reaction mixture. The reaction mixture was stirred for 4 h at room temperature. The solids were removed by filtration and the filtrate was concentrated under reduced pressure. The residue was purified by a silica gel chromatography with ethyl acetate/petroleum ether (1/10) as the eluent to yield 1 g (34%) of the title compound as a colorless oil.
