실험 절차

A solution of crude 3-Fluoro-1-[3-(4-nitro-phenoxy)-propyl]-pyrrolidine (6.316 g, ˜24 mmol) was dissolved in absolute ethanol (180 mL) and to this solution was added hydrazine monohydrate (˜7.9 mL) followed by the addition of a small portion of Raney nickel (˜1 mL). The reaction mixture was heated to 50° C. with stirring for ˜2 h at which point all gas evolution had ceased. The reaction mixture was filtered through celite to remove the Raney nickel. The filtrate was concentrated in vacuo to give 4-[3-(3-Fluoro-pyrrolidin-1-yl)-propoxy]-phenylamine as a brown oil which was subjected to flash silica gel chromatography (CHCl3 to CHCl3:MeOH, 1:40 gradient eluant). Pure 4-[3-(3-Fluoro-pyrrolidin-1-yl)-propoxy]-phenylamine was isolated as a reddish oil (4.033 g, 79%).
