To 90.0 g. (0.26 mole) of 4-cyclohexylaminomethyl-4,5-dihydro-3,3-diphenylfuran-2-(3H)one in 500 ml. of isooctane was added 1.0 g. of sodium hydride (57% in mineral oil) as a catalyst and the mixture was refluxed overnight. Upon cooling a solid precipitated and the isooctane was decanted from the solid. The solid was recrystallized from isopropyl alcohol, weighed 66.0 g. (73% yield) and melted at 148°-150° C.
