Potassium Hydroxide → 4-(6-Hydroxy-2,2,3,3,4,4,5,5-octafluorohexyloxy)-2,3,5,6-tetrafluorobenzeneamine

Participants

Reaction Steps

A solution of the 4-(6-hydroxy-2,2,3,3,4,4,5,5-octafluorohexyloxy)-2,3,5,6-tetrafluoronitrobenzene (2.0 g) in ethanol (50 mL) was treated with tin (II) chloride dihydrate (9.9 g) at 60° C. for 18 hrs. under a nitrogen atmosphere. The mixture was diluted with ice water, basified with potassium hydroxide (10.1 g) in water (80 mL) and extracted with ethyl ether. The extracts were washed with water and brine, dried (K2CO3), and concentrated to an oil. The oil was purified by chromatography to give 4-(6-Hydroxy-2,2,3,3,4,4,5,5-octafluorohexyloxy)-2,3,5,6-tetrafluorobenzeneamine as an oil (1.77 g).
