Versuchsvorschrift

A mixture of (3-benzyloxy-1-phenyl-1H-pyrazol-5-yl)methanol (11.20 g), activated manganese dioxide (30.00 g) and tetrahydrofuran (300 mL) was stirred overnight at room temperature. The insoluble material was removed by filtration, and the mother liquid was concentrated. The residue was subjected to silica gel column chromatography to give 3-benzyloxy-1-phenyl-1H-pyrazole-5-carbaldehyde (10.10 g, yield 91%) as a pale-yellow oil from a fraction eluted with ethyl acetate-hexane (1:2, v/v).
