実験手順

Step G (1): 3-amino-5-(methoxycarbonyl)benzoic acid. A suspension of 3-(methoxycarbonyl)-5-nitrobenzoic acid (20.0 g) and palladium on carbon (5 wt %, 4.0 g) in MeOH (600 mL) was shaken in hydrogenator under hydrogen at 50 psi for 3 h. The mixture was filtered and concentrated in vacuo to give the title compound: 1H NMR (CD3OD, 500 MHz) δ ppm 3.90 (3H, s), 7.52 (1H, m), 7.55 (1H, m), 7.92 (1H, m). MS (ESI) (M−H)− 194.08.

後処理

  1. filtrationThe mixture was filtered
