Reaction Steps

5 g (7.6 mmol) of 11-{4-[(Z)-2-(1,3-benzodioxol-5-yl)-2-cyanoethenyl]-2-methoxyphenoxy}undecyl 3,5-dinitrobenzoate are dissolved in a mixture of 84 ml of DMF and 9 ml of water. 15.7 g (58 mmol) of ferric chloride hexahydrate are added. 6.31 g (97 mmol) of zinc powder are added portionwise within 30 min. The mixture is allowed to react for 2 hours. The reaction mixture is then partitioned between ethyl acetate and water and filtered. The organic phase is washed repeatedly with water, dried over sodium sulfate, filtered and concentrated by rotary evaporation. Filtration of the residue on silica gel using toluene:ethyl acetate(1:3) as eluant and yielded 2.8 g (61%) of 11-{4-[(Z)-2-(1,3-benzodioxol-5-yl)-2-cyanoethenyl]-2-methoxyphenoxy}undecyl 3,5-diaminobenzoate as a white powder.
