Procedure

To a suspension of 14 g (0.024 mole) 1-(p-methoxyphenylazo)-3-octadecanesulfonyl-2-naphthol in 500 ml hot ethanol was added a solution of 12 g (0.060 mole) sodium dithionite in 60 ml water. The mixture was stirred and refluxed for one hour, then cooled and filtered to give 11 g of solid, which can be recrystallized from hexane to give a solid, m.p. 84°-88° C.
