Procedure
Ethyl 2-methylamino-1,3-thiazole-4-carboxylate (300 mg, 1.611 mmol) was dissolved in THF/water mixture and 1M litium hydroxide (3.22 ml, 3.22 mmol) was added. The reaction mixture was stirred at RT for 3 hours, pH was adjusted to acidic and the mixture was evaporated to dryness to yield the title compound. 1H-NMR (400 MHz; DMSO-d6): δ 2.84 (s, 3H), 7.46 (s, 1H), 7.90 (bs, 1H).
