Reaction Steps
A suspension of 2-[2-hydroxy-2-(3-methyl-5-pyridin-2-yl-3H-[1,2,3]triazol-4-yl)-ethyl]-4-methyl-thiazole-5-carboxylic acid (152 mg, 0.44 mmol) in sulfuric acid (conc., 2.59 mL, 48.4 mmol) was heated at 160° C. under Ar for 7 h. After cooling to room temperature the mixture was poured into ice, adjusted to pH 4 with NaOH (6 N) and extracted with ethyl acetate and the combined organic extracts washed with brine, dried over sodium sulphate, filtered and evaporated to afford the title compound (114 mg, 79%) as an a yellow solid after trituration from methanol-water. MS: m/e=326.2 [M−H]−.
