Reaction Steps

A mixture of 3 g of 4-chloro-1-(2-methyl-4-fluorophenyl)-1,1-ethylenedioxybutane, 2.3 g. of 4-oxo-1-phenyl-1,3,8-triazaspiro[4,5]decane, 1.4 g of anhydrous potassium carbonate, 0.05 g of potassium iodide and 30 ml of dimethylformamide was refluxed for 3 hour. The resulting mixture was poured into ice water. The precipitated crystals were collected by filtration and washed with water to give 8-[4-(2-methyl-4-fluorophenyl)-4,4-ethylenedioxybutyl]-4-oxo-1-phenyl-1,3,8-triazaspiro[4,5]decane as crude crystals (5 g).
