The 2-nitrobenzamide of Step D (1.70 g, 7.6 mmol) was hydrogenated over 5% palladium on carbon in 40 mL of ethanol at 345 kPa (50 psi). When the uptake of hydrogen ceased the reaction was filtered through Celite® filter agent and the Celite® was washed with ether. The filtrate was evaporated under reduced pressure to afford 1.41 g of the title compound as a solid melting at 149–151° C.
