Procedure

To a solution of 1-methyl-2-pyrrolecarboxylic acid (1.03 g, 8.22 mmol) in MeOH (5 mL) and dioxane (5 mL) at room temperature, trimethylsilyldiazomethane (2M in ether, 5.0 mL, 10.0 mmol) was added. After being stirred at room temperature for 1 h, the mixture was concentrated in vacuo to give methyl 1-methyl-2-pyrrolecarboxylate as a volatile oil (1.14 g).
