実験手順

2-(3-Nitrobenzoyl)-3-carboxypyridine was dissolved in 20 ml of methylene chloride and the solution was cooled in an ice/water bath. Diazomethane (25 ml, 0.33M) was added to the solution and stirred for 2 hours. The solvent was removed and the residue chromatographed (methylene chloride) yielding 0.26 g of 2-(3-nitrobenzoyl)-3-methoxycarbonylpyridine.
