Procedure
Trifluoroacetic acid (10 ml) was added to 4iodo-benzoic acid N′-(2,2-dimethyl-propionyl)-hydrazide (Intermediate 13) (1 g, 2.76 mmol) and stirred at room temperature for 2 hours. The trifluoroactic acid was removed in vacuo and the residue partitioned between ethyl acetate (50 ml) and saturated aqueous sodium bicarbonate solution (50 ml). The organic layer was washed with water (50 ml), brine (50 ml), dried over magnesium sulfate, filtered and the solvent removed in vacuo. The desired product was obtained as a white solid (0.55 g, 2.1 mmol).
