Reaktionsschritte

In accordance with the synthesis process (B), 500 mg (2.84 mmol) of 1-phenyl-imidazolidin-2,4-dione were dissolved in 20 ml of pyridine. To the solution, 500 mg (2.86 mmol) of p-chlorobenzoyl chloride were added dropwise while chilling with ice water. The resultant mixture was stirred at 0°-5° C. for 2 hours, and dilute hydrochloric acid was then added to the reaction mixture. Crystals deposited were collected by filtration by means of suction. These crude crystals were recrystallized from n-hexane/ethyl acetate, thereby obtaining 220 mg (yield: 25%) of the title compound.
