A solution of methyl 2-[(4-hydroxybutyl)amino]-3-nitrobenzoate (66.5 g, 248 mmol) in tetrahydrofuran (1600 mL) was stirred in the presence of 10% palladium on carbon (50% wet; 6.80 g) under hydrogen atmosphere at room temperature for 5 h. The catalyst was removed by filtration, and the filtrate was concentrated in vacuo to give the title compound as a yellow oil (58.4 g, 245 mmol, 99%).
