    Concentraciónthe filtrate was concentrated by evaporation under reduced pressure

Procedimiento

A solution of 30.8 g of methyl 4-nitrophenoxyacetate [prepared as described in step (a) above] in 500 ml of methanol was shaken in an atmosphere of hydrogen and in the presence of 5.0 g of 10 w/w palladium-on-charcoal for 6 hours. At the end of this time, the reaction mixture was filtered and the filtrate was concentrated by evaporation under reduced pressure, to give 25.8 g of the title compound having an Rf value=0.79 (on thin layer chromatography on silica gel; developing solvent: ethyl acetate).
