Reaction Steps
A mixture of 12 g of ethyl p-(2-phenoxyethylamino)-benzoate, 12 g of potassium hydroxide and 200 ml of ethanol-water (9:1) is refluxed for 3.5 hours. The solution is acidified while hot with concentrated hydrochloric acid, diluted with water, cooled, filtered and the solid washed with water to give crystals, mp 172°-175° C. Recrystallization from ethanol gives off-white crystals, mp 174°-176° C.
