Procedure
To a solution of 1-azatricyclo[3.3.1.13,7]decane-4-carboxylic acid hydrochloride in EtOH was added concentrated sulfuric acid, followed by heating under reflux for 18 hours. The reaction liquid was concentrated under reduced pressure and then diluted with EtOAc. The EtOAc layer was washed with an aqueous NaHCO3 solution and brine in this order, dried over MgSO4, and then concentrated under reduced pressure to obtain a yellow oily substance. This was purified by silica gel column chromatography (CHCl3:MeOH) to obtain ethyl 1-azatricyclo[3.3.1.13,7]decane-4-carboxylate as a yellow solid.
