Reaction Steps

A solution of 2 g. of ethyl p-[2-(cyclopentyl)ethylamino]benzoate in 50 ml. of ethanol:water (9:1) containing 2 g. of potassium hydroxide is stirred at the reflux temperature under argon atmosphere for 3 hours. The chilled solution is acidified with concentrated hydrochloric acid, diluted with 45 ml. of water, and filtered to furnish 1.52 g. of white crystals. Recrystallization from ethanol/hexane provided product as white crystals.
