Reaction Steps

A mixture of 2 g 1-oxa-3,8-diazaspiro[4.5]-decan 2-one, 3.12 g 2,3-epoxypropyl 1-naphthyl ether, 5 ml methanol and 10 ml toluene is heated at reflux for 5 hours. The solvent is removed by evaporation in vacuum. The residue is filtered through 20 g silica gel with 5% methanol/methylene chloride. Evaporation of solvent and recrystalization from ethyl acetate affords 3.35 g 8-[3-(1-naphthyloxy)-2-hydroxypropyl]-1-oxa-3,8-diazaspiro[4.5]decan-2-one, mp 178°-179°.
