Procedure

A mixture of methyl 4-{3-[1-(1,3-benzothiazol-6-yl)cyclopropyl][1,2,4]triazolo[4,3-b][1,2,4]triazin-6-yl}benzoate (80.0 mg, 0.19 mmol) and lithium hydroxide monohydrate (16.0 mg, 0.37 mmol) in methanol (3.0 mL) and water (1.0 mL) was stirred at RT for 4 h. The mixture was adjusted with 1N HCl to pH=5. The volatiles were removed under reduced pressure, and dried in-vacuo to give a crude product which was directly used in the next step without further purification. Analytical LCMS: (M+H)+=415.0.
