Procedure
11.95 g (36.85 mmol) of nitro compound from Example XIV are hydrogenated in 500 ml of methanol/ethanol mixture using 550 mg of palladium/active carbon (10%) at 3 bar. The mixture is filtered through kieselguhr, the solvent is removed in vacuo and the product is purified by chromatography (toluene/ethyl acetate).
Workup
- filtrationThe mixture is filtered through kieselguhr
- customthe solvent is removed in vacuo
