Stirring was continued for 30 minutes and the mixture was allowed to stand at room temperature for 60 hours. The resulting precipitate was collected by filtration, washed with ether, crushed with a mortar and pestle, and again washed with ether. The product was dried in vacuo to give a white crystalline solid (11.7 g, 91%), which was used without further purification.
