Procedure
To a mixture of 5-trifluoromethylpyridin-2,3-diamine (1.2 g) and pyridine (20 ml), methyl chloroformate (0.63 ml) was added under ice-cooling. The mixture was heated to room temperature, stirred for 8 hours, and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography to give 628 mg of methyl (2-amino-5-trifluoromethylpyridin-3-yl)-carbamate.
