The solution was evaporated in vacuo to give a black oil that was then dissolved in dichloromethane and then saturated sodium bicarbonate solution was added. A precipitate was formed which was collected by filtration as a yellow crystalline solid. The solid was triturated with ether then filtered to give 11.3 g of the product of the example as yellow crystals, mp 274°-277° C.
