Versuchsvorschrift
1-Phenyl-cycloheptanecarboxylic acid (Example 1c) (4.15 g) was refluxed in methanol (150 mL) and concentrated hydrochloric acid (5 mL) for 24 hours. The solvent was evaporated and the residue was dissolved in ether (100 mL) which was washed with water (100 mL), saturated sodium bicarbonate (50 mL) and water (100 mL), dried (MgSO4) and evaporated to afford the sub-titled compound (3.5 g) as an oil.
