실험 절차

0.46 g. (1.47 mmoles) of 1-Hydroxy-3-n-pentyl-6,6,9-trimethyl-10a,6a,7,8 -tetrahydrodibenzo[b,d]pyran, 0.31 g. (1.47 mmoles) of γ-piperidinobutyric acid hydrochloride and 0.32 g. (1.55 mmoles) of dicyclohexylcarbodiimide were combined in 25 ml. of methylene chloride and stirred at room temperature for 4 hours. The insoluble by-product of dicyclohexylurea was removed by filtration and the methylene chloride was evaporated to give a gummy yellowish residue. The gummy material was triturated several times with petroleum ether and dried in vacuo to give 350 mg. of product as a colorless foam-like solid. The sample was pure by thin-layer chromatography (10% MeOH/CHCl3) and the infrared spectrum was consistent with the proposed structure.
