Procedure

To a suspension of 6-aminonicotinic acid (1.00 g, 7.24 mmol) in MeOH (20 ml) and MeCN (10 ml) was added 10% solution of trimethylsilyldiazorniethane in CH2Cl2 (25 ml) at room temperature. After stirring at room temperature for 0.5 h, the solvent was evaporated to give crude methyl 6-aminonicotinate as a yellow solid. Title compound was prepared from this crude methyl 6-aminonicotinate in 17% yield according to a procedure similar to that described in Preparation 6.
