The reaction mixture was concentrated under reduced pressure, the residue was dissolved in water and extracted with diethyl ether. The pH of the aqueous layer was adjusted between 2 and 3 by addition of a solution of hydrochloric acid 6N until a precipitate was formed. The suspension was extracted twice with ethyl acetate and the combined organic layers were dried over sodium sulfate and concentrated under reduced pressure to give 0.041 g (51%) of the title compound.
