| | Synthesis | Step B / Intermediate B9: Synthesis of 3,4,5-trimethoxyaniline
To a solution of 1,2,3-trimethoxy-5-nitrobenzene (6.64 g, 31.2 mmol) in ethanol (250 mL) was added palladium carbon (10%, 300 mg) and hydrazine hydrate (85%, 5.7 mL). The reaction mixture was heated to reflux for 1 hour after gas release ceased. Upon completion of the reaction, the mixture was cooled to room temperature and the catalyst was removed by filtration followed by evaporation of the solvent to afford 3,4,5-trimethoxyaniline (5.5 g, 96.4% yield) as a white solid. The product was characterized by 1H NMR (400 MHz, DMSO-d6): δ 5.86 (s, 2H), 4.82 (br, 2H), 3.64 (s, 6H), 3.50 (s, 3H). | | References | [1] Patent: WO2012/92880, 2012, A1.
