Participants

Reaction Steps

Sodium hydride (0.01 g) is added to a solution of cyclopentyl-[(2R,6R)-8-hydroxy-6-methyl-1,2,5,6-tetrahydro-4H-2,6-methano-benzo[d]azocin-3-yl]-methanone (0.10 g) in tetrahydrofuran (6 mL; alternatively N,N-dimethylformamide may be used). The mixture is stirred for 30 min at room temperature before methyl iodide (25 μL) is added. The resulting solution is stirred at room temperature overnight. Then, water is added and the resulting mixture is extracted with dichloromethane. The combined extracts are dried (Na2SO4) and the solvent is evaporated. The residue is purified by chromatography on silica gel (cyclohexane/ethyl acetate).
