Procedure

To a mixture of 17 g (0.031 mole) 1-(p-methoxyphenylazo)-3-octadecyloxy-2-naphthol and 700 ml ethanol was added a solution 13.5 g (0.070 mole) sodium dithionite in 80 ml water. The mixture was refluxed for 2.5 hours, cooled, and filtered. The while solid, 11 g, was recrystallized from a mixture of hexane and ethyl acetate to give an off-white solid, m.p. 97°-99° C.
