实验步骤: To cyclohexanone (259 mL) was added formaldehyde (37.2 mL of a 37% aqueous solution) and dimethylamine hydrochloride (40.8 g). The stirred mixture was slowly heated and refluxed for 1 h. After cooling to ambient temperature H2O was added, and the mixture was extracted twice with Et2O. The aqueous layer was made basic by addition of 50% aqueous NaOH (27.5 mL), and subsequently extracted twice with DCM.
