The above 4-nitrobenzene (2.0 g, 9.5 mmol) was dissolved in ethanol (50 mL) and tin(II) chloride dihydrate (10.7 g, 48 mmol) was added and the mixture was refluxed for 24 hours. After cooling, the mixture was concentrated in vacuo. The residue was dissolved in ethyl acetate (40 mL) and 1N aqueous sodium hydroxide (180 mL). This mixture was filtered through celite. The aqueous phase was extracted with ethyl acetate (2×50 mL) and the combined organic extracts were dried (MgSO4) and concentrated in vacuo to afford 0.88 g (52%) of 4-cyclopropylmethoxyaniline.
