2-Nitro-4-vinyl-benzoic acid methyl ester → Methyl 2-amino-4-ethylbenzoate

Participants

Reaction Steps

A solution of 2-nitro-4-vinyl-benzoic acid methyl ester (820 mg, 3.96 mmol) in MeOH (15 mL) was shaken under H2 (0.1 bar) in the presence of Pd/C (10%, 0.2 g) at 50° C. for 5 h. After cooling to r.t., the reaction mixture was filtered and the solvent was removed in vacuo to provide the title product (680 mg, 96%) which was used in the next step without further purification. ESI-MS: m/z 180.1 [M+H]+, rt 5.13 min
