실험 절차

A mixture of methyl 2-[(2-hydroxyethyl)amino]-3-nitrobenzoate (10.0 g, 41.6 mmol) and 10% palladium on carbon (0.10 g) in tetrahydrofuran (200 mL) was stirred under hydrogen atmosphere at room temperature for 24 hr. Catalyst was removed by filtration and the filtrate was concentrated in vacuo to give the title compound (36 mg, 0.090 mmol, 90%) as a pale yellow oil. This product was used next steps without purification.
