Tin (II) chloride (13.6 g (60 mmole)) is added to a solution of 4-(3-Nitro-phenoxymethyl)-biphenyl (4.6 g, 15 mmole) in 120 ml methanol. The reaction mixture is refluxed for 12 hr. The reaction is cooled to room temperature, 4 N of NaOH solution is added with stirring to adjust pH=8. The resulting mixture is filtered through a plug of CELITE, the filtrate concentrated and taken up in ethyl acetate. The organic layer is washed with brine and dried over Na2SO4, and concentrated. The resulting solid is washed with little methanol to yield 3-(Biphenyl-4-ylmethoxy)-aniline as a yellow solid. MS: 276(M+1).
