Procedure

3-Nitrobenzoic acid (Aldrich)(1 g; 5.98 mmol; 1 eq.) is dissolved in toluene (15 ml). Timethylsilyl diazomethane in toluene and MeOH (1/1)(9.0 ml; 2 M; 17.95 mmol; 3 eq.) is added dropwise. The solution is stirred at rt for 1.5 h. Solvents are removed affording methyl 3-nitrobenzoate as a yellow powder (940.7 mg; 87%).
