Reaction Steps

17.9 grams of the compound of Example 16 was stirred together with white oil at 165° to 180° for two hours until little CO2 evolution could be detected. The reaction mixture was cooled to 50° and stirred thoroughly together with 5.2 grams of sodium bicarbonate dissolved in 100 ml of water until no foaming took place and all solids had dissolved. The reaction mixture was diluted with 50 ml of n-hexane and the upper organic phase separated from the lower aqueous phase. The organic phase was washed with water, the wash water being combined with the aqueous phase. The combined aqueous phase was then washed with n-hexane, clarified by filtration through filtercel, and added dropwise to about 150 ml of cold 6 N aqueous hydrochloric acid so that a granular off-white precipitate was obtained. The product was used as such after drying in the vacuum oven at 60° and 3 mm Hg. overnight.
