A solution of LiOH.H2O (1.38 g, 33 mmol) in water (33 mL) was added in one portion to a suspension of methyl 2-amino-5-chloronicotinate (6.08 g, 27 mmol) in MeOH (110 mL). The reaction mixture was stirred at 70° C. for 24 hours, and gradually became homogeneous. The solvents were removed under reduced pressure, and after the resulting white solid was dried under vacuum (<1 mmHg) to constant weight, 5.51 g (95%) of lithium 2-amino-5-chloronicotinate A55 was obtained.
