Procedure
A mixture of 4-chloro-1-(2,4-difluorophenyl)-1,1-ethylenedioxybutane (5.3 g), 4-oxo-1-phenyl-1,3,8-triazaspiro[4,5]decane (4.6 g), anhydrous potassium carbonate (0.1 g) and dimethylformamide (58 ml) was heated under refluxing for 2.5 hours. After cooling, the reaction mixture was poured into cold water (400 ml) with vigorous stirring, and the precipitate was collected and washed with water to yield 4-(4-oxo-1-phenyl-1,3,8-triazaspiro[4,5]decan-8-yl)-1-(2,4-difluorophenyl)-1,1-ethylenedioxybutane. M.P. 58° - 62°C.
