A mixture of [4-(4-fluorophenyl)-1-methyl-1H-pyrazol-5-yl]methanol (250 mg), activated manganese dioxide (1.0 g) and tetrahydrofuran (10 ml) was stirred at room temperature for 3 hrs. The reaction mixture was filtered, and the organic layer was concentrated to give 4-(4-fluorophenyl)-1-methyl-1H-pyrazole-5-carbaldehyde (172 mg, yield 70%) as pale-yellow crystals.
