Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A suspension of 2.55 g of 1-(3-methoxypropoxy)-2-nitrobenzene, 3.72 g of ammonium formate in 25 ml of methanol is hydrogenated at reflux in the presence of 0.26 g of 10% Pd/C over 1.5 hours. The reaction mixture is cooled and clarified by filtration, and the filtrate is concentrated by evaporation. The residue is dissolved in diethyl ether, washed with water (2×) and brine, dried over sodium sulphate and concentrated by evaporation. The title compound is obtained as a red oil from the residue by means of flash chromatography (SiO2 60F). Rf=0.30 (1:2 EtOAc-heptane); Rt=228. The reaction mixture is cooled clarified by filtration the filtrate is concentrated by evaporation The residue is dissolved in diethyl ether washed with water (2×) and brine dried over sodium sulphate concentrated by evaporation
