Methyl 2-chloro-4-nitrobenzoate → Methyl 4-Amino-2-chlorobenzoate

Participants

Reaction Steps

A solution of 4-nitro-2-chlorobenzoic acid methyl ester (Aldrich, 700 mg, 3.24 mmol) in ethyl acetate (50 mL) was treated with 10% Pd/C (50 mg) and hydrogenated at 1 atmosphere for 3 hrs. The mixture was filtered and concentrated to give a light yellow solid which was directly used for the next step.
