Mode opératoire

To 150 mL of sodium carbonate 1N solution, methyl 2-((5-methoxy-6-nitropyridin-2-yl)methylthio)acetate (10 mmol, 2.72 g) was added and the mixture was reacted at 50° C. for 16 hrs. The mixture was evaporated in vacuo to give 2-((5-methoxy-6-nitropyridin-2-yl)methylthio)acetic acid. Yield 97%; m.p. 239-230° C.
