Reaktionsschritte
A mixture of methyl 2-bromo-1,3-thiazole-4-carboxylate (4.2 g, 18.9 mmol), THF (120 mL) and 1N lithium hydroxide (50 mL) was heated at 70° C. for 1 h. The organic solvent was removed in vacuo. The residual aqueous solution was cooled to 0-5° C. and acidified to pH1 with 1N HCl solution. The tile compound was obtained by filtration, as a white solid.
