Versuchsvorschrift
A mixture of methyl-4-amino-5-nitropicolinate (200 mg, 1.01 mmol) and NaOH (aq, 1M, 2.0 mL, 2.0 mmol) in methanol was stirred at ambient temperature for 10 min. The mixture was acidified by addition of HCl (aq, 1M, 2.1 mL, 2.1 mmol) and concentrated i. vac. and the aqueous residing mixture filtered. The solid was washed with water and dried i. vac.
