실험 절차

4.0 g. (10.1 mm.) of 5,5-dimethyl-10-hydroxy-8-(3-methyl-2-octyl)-2-(2-propynyl)-1,2,3,4-tetrahydro-5H-[1]benzopyrano[3,4-d]pyridine, 2.10 g. (10.1 mm.) of γ-morpholinobutyric acid hydrochloride and 2.18 g. (10.6 mm.) of dicyclohexylcarbodiimide were added to 200 ml. of methylene chloride. The reaction mixture was stirred at room temperature for 16 hours and after cooling the by-product of dicyclohexylurea was removed by suction filtration. The mother liquor was evaporated to give a residue which after the usual work-up was converted to a dihydrochloride by the addition of an ether solution of hydrogen chloride. Recrystallization from methylene chloride/diethyl ether gave a total of 3.23 g. (52%), m.p. 154°-160° C. The nuclear magnetic resonance and infrared spectra were in agreement with the proposed structure; the material was pure by thin layer chromatography (10% MeOH/CHCl3).
