Reaction Steps

General Procedure E To a solution of ethyl 4-[ethyl(3,5,8,8-tetramethyl-5,6-dihydronaphthalen-2-yl)amino]benzoate, (Compound 19, 0.17 g, 0.45 mmol) and 5 mL of absolute ethyl alcohol was added aqueous 5 M KOH (2 mL). The resulting solution was heated in an 60° C. bath for 24 h. The solution was cooled to room temperature, diluted with water and washed once with 2:1 hexane:ethyl acetate solution, and the layers were separated. The aqueous layer was acidified with HCl 2 N to pH=0-1 and the product extracted three times with ethyl acetate. The combined organic extracts were washed with brine, dried over MgSO4, and filtered. The solvent was removed to give 0.042 g (92%) of the title compound as an off-white solid.
