Versuchsvorschrift
A solution of 4-nitro-1-(tetrahydro-2H-pyran-4-yl)-1H-pyrazole (568 mg, 2.88 mmol, 1 equiv) in methanol was circulated through a H-Cube® Continuous-flow hydrogenation reactor (ThalesNano) fitted with a palladium on carbon catalyst cartridge at 50° C. The collected solution was concentrated in vacuo to afford product as pink solid (458 mg, 95% yield). LCMS (ESI) m/z: 168.0.
