To a solution of ethyl 5-methoxythiazole-2-carboxylate (73 mg, 0.39 mmol) in THF (1 ml) 1 M LiOH-solution (0.78 ml, 0.78 mmol) was added. Reaction mixture was stirred at RT for 1 h. Reaction was quenched by adding 1 M HCl solution until pH was about 5. Solvents were evaporated and thus obtained crude title compound was used without purification. 1H-NMR (400 MHz; d6-DMSO): δ 3.88 (s, 3H), 7.12 (s, 1H).
