Potassium Iodide → HCID 19814281, compound

Participants

Reaction Steps

A mixture of 11.8 g of 4-methylene-3-(1-naphthyl)-2-oxo-1-oxa-3,8-diazaspiro[4,5]decane, 5.8 ml of benzyl chloride, 4.2 g of anhydrous sodium hydrogen carbonate, 0.5 g of potassium iodide and 177 ml of methyl ethyl ketone is refluxed under argon while stirring for 18 hours. After termination of the reaction the mixture is cooled down and the solvent is evaporated under reduced pressure. After adding chloroform and water to the residue and separating the phases, the organic layer is washed with water to chloride-free, dried over anhydrous magnesium sulfate and evaporated under reduced pressure. After recrystallizing the residue under clarifying by activated carbon the title substance is obtained in 84% yield, m.p.: 130°-131° C.
