Procedure
To a solution of 6-methyl-5-nitropicolinic acid (31C, 500 mg, 2.75 mmol) in methanol (10 ml) was added Pd/C (50 mg). The solution was stirred at r.t. under H2 atmosphere for 1 h, when LC-MS showed that s.m. was consumed. Then the mixture was filtered and concentrated to give the crude product which was used to the next step without further purification. LC-MS: m/z 153 (M+H)+
