Participants

Reaction Steps

Methyl 5-(N-(5-cyclopropyl-2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-6-yl)methylsulfonamido)-2-nitrobenzoate (3.2 g, 5.50 mmol) was dissolved in methanol (50 mL), hydrogenation was carried out under H2 ((H2 balloon) in the present of 10% Pd/C (0.586 g, 0.550 mmol) at room temperature. The mixture was stirred for 6 hours, It was then filtered by pass through a pad of Celite. Concentrated under reduced pressure, it was rinsed twice with hexane to give the desired product (3.0 g, 98%) as a yellow solid which was used for the next step without further purification. LCMS (m/z, ES+)=552 (M+H+).
