Reaction Steps

Add trans-4-aminocyclohexanol (230 g; 2.0 mol) to γ-butyrolactone (140 mL; 1.82 mol) in a 1 L round-bottom flask equipped with large magnetic stirrer, thermometer and condenser/nitrogen bubbler. Heat at 190° C. for 68 hours. Cool to ambient temperature and dissolve in water (1 L). Extract into dichloromethane (10×1.5 L). Dry the extracts over magnesium sulfate, filter and evaporate to a brown solid. Triturate with diethyl ether to afford 144.7 g (43%) of the title compound: LC-MS (M+1=184).
