Procedure
A mixture of Intermediate 2-(2-fluoro-3-nitrophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (500 mg), 10% palladium on carbon (50 mg) and ethyl acetate (20 ml) was stirred under 1 atmosphere of hydrogen for 16 h. The mixture was sparged with nitrogen and filtered. The filtrate was concentrated to provide the title compound, which was used without further purification. MS m/z 237.1 (M+1).
