53.4 Grams of 1-ethoxycarbonyl-4-decylpiperazine is combined with 300 ml. of concentrated hydrochloric acid and refluxed with stirring under a nitrogen atmosphere for approximately 48 hours. After cooling to room terperature the solvents are removed under reduced pressure. The resulting solid is suspended in ethanol, filtered, and air-dried to yield 1-decylpiperazine.
