반응 단계

A mixture solution of 14.5 mL (0.134 mol) of methyl acetoacetate and 20.2 g (0.134 mol) of cyclohexylhydrazine hydrochloride was stirred for 2 hours at 120° C., and the mixture was cooled. Then, the reaction mixture was neutralized with 30 mL of 4M-sodium hydroxide solution and extracted with ethyl acetate. The organic layer was washed with water and saturated saline solution and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, and the resulting residue was treated with hexane. The resulting precipitate was collected to give 19.0 g (79%) of the titled compound.
