Reaction Conditions

Reaction Steps

A mixture of 18.9 g (0.1 mole) of 5-benzyl-1-oxa-5-azaspiro[2.4]heptane and 15.6 g (0.11 mole) of 1-naphthol was heated to 115° C. to form a homogenous melt, which was stirred with a magnetic stirrer for 2 hours. Upon cooling, a paste-like material formed. The reaction mixture was dissolved in benzene, filtered and ligroin added to the filtrate until cloudy. The suspension was warmed to solution and allowed to stand in the refrigerator overnight. The precipitate was collected by filtration to give 20.2 g (60%) of crude material. A portion of this solid was recrystallized from 190 ethanol to give a white crystalline solid, m.p. 129.5°-130° C.
