Reaction Steps

A solution of 5 g. of 2-cyclopentylethyl methanesulfonate and 8.59 g. of ethyl p-aminobenzoate in 30 ml. of hexamethylphosphoramide is stirred at 110° C. under argon atmosphere for 18 hours. The cooled solution is diluted with 30 ml. of water and the resulting tan solid is collected by filtration. Recrystallization from ethanol-water furnishes ethyl p-[2-(cyclopentyl)ethyl]aminobenzoate as off-white crystals.
