Procedure

A solution of 4.8 g of ethyl p-{[6-(2-naphthyloxy)-hexyl]amino}benzoate and 4.8 g of potassium hydroxide in 100 ml of 95% ethanol is refluxed for 3 hours. The solution is cooled, diluted with water and acidified with concentrated hydrochloric acid. The mixture is filtered and the solid washed with ethanol with water and recrystallized from ether-methylene chloride and acetone to give crystals, mp 157°-159° C.
