Procedure
To 50 ml of MeOH is added drop wise acetyl chloride (3 ml) at room temperature. After 15 min, 2-amino-6-methylisonicotinic acid (2.3 g) is added and the mixture is stirred overnight at 50° C. After concentrating the solution, the resulting residue is suspended in acetone and then filtered and dried at 50° C. in vacuum, to yield 2-amino-6-methylisonicotinic acid methyl ester (4.1 g). HPLC: Rt=0.91 min (method D)
