실험 절차

3.54 g. (11.27 mmole) of 1-Hydroxy-3-n-pentyl-6,6,9-trimethyl-10a,6a ,7,8-tetrahydrodibenzo[ b,d] pyran, 2.86 g. (11.27 mmole) of γ-morpholinobutyric acid hydrobromide and 2.50 g. (12.12 mole) of dicyclohexylcarbodiimide were combined in 200 ml. of methylene chloride and stirred at room temperature for 24 hours. The reaction mixture was cooled and the by-product of dicyclohexylurea was removed by filtration. The volume of methylene chloride was reduced and 25 ml. of cyclohexane was added. The mixture was cooled and the small amount of solid which formed was removed by filtration. All solvents were removed on a rotary evaporation and the residue was dried in vacuo. The resulting foamy material was dissolved in a mixture of benzene and ether and placed in cold storage to yield 3.0 g. (50%) of product as colorless crystals, m.p. 103°-105°C. The compound gave a Rf 0.5 in 5% MeOH/CHCl3. The infrared and nuclear magnetic resonance spectra were consistent with the proposed structure.
