Methyl iodide → 4-[3-[3-[2-(1-Adamantyl)ethyl]-3-pentylureido]propyl]-1-methylpyridinium iodide

Participants

Reaction Steps

Methyl iodide (90 μl, 1.5 mmol) was added to a solution of 1-[2-(1-adamantyl)ethyl]-1-pentyl-3-[3-(4-pyridyl)propyl]urea (Compound No. 1-1) (0.30 g, 0.73 mmol) in acetone (1.5 ml) at room temperature, and the mixture was stirred overnight. The solvent was evaporated under reduced pressure from the reaction mixture, and the precipitated crystals were filtered off with ethyl acetate to give 389 mg (96%) of the titled compound.
