Reaktionsschritte
1.8 ml of concentrated sulphuric acid were added to a solution of 4.00 g (25.3 mmol) of 4-methoxycyclohexanecarboxylic acid in 32 ml of methanol, and the resulting reaction solution was heated under reflux overnight. The mixture was cooled to room temperature and the pH was adjusted to 7-8 using saturated aqueous sodium bicarbonate solution. The mixture was then extracted three times with 70 ml of ethyl acetate. The combined organic phases were dried over sodium sulphate and filtered, and the solvent was removed under reduced pressure. The crude product corresponded to the title compound. Yield: 4.30 g (99% of theory)
