실험 절차

To 9.69 gm. (0.06 mole) of 3-amino-1-cyclohexylpyrrolidine in 50 ml. of chloroform was added dropwise a solution of 8.4 gm. (0.046 mole) of 1-naphthalenecarbonyl chloride in 50 ml. of chloroform. The reaction mixture was concentrated under reduced pressure and the residue was partitioned between ethyl acetate containing 10% isopropyl ether and dilute hydrochloric acid. The separated acid layer was made basic with dilute sodium hydroxide solution and extracted with chloroform. The chloroform solution was dried over sodium sulfate, concentrated and the residue crystallized from ethyl acetate. The product weighed 3.8 gm. (25%) and melted at 119°-120° C.
