Procedure
trans-(1R,2S)-2-(3,4-Difluorophenyl)cyclopropanaminium (2R)-2-hydroxy-2-phenylethanoate (258 kg) and potassium carbonate (280 kg) were dissolved in water (1024 kg) and charged to the solution of 2-({(3aR,4S,6R,6aS)-6-[7-chloro-5-(propylthio)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-3-yl]-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl}oxy)ethanol solution from example 5 above with a rate that kept the temperature of the reaction ≦30° C. After full conversion was reached (≧99.9%) the water layer was separated off. The organic layer was washed with a mixture of acetic acid (96 kg) and sodium chloride (96 kg) in water (768 kg) and then washed again with a mixture of acetic acid (32 kg) and sodium chloride (22 kg) in water (952 kg). A third wash of the organic layer was done with sodium chloride (96 kg) in water (864 kg), whereafter the organic layer was used in the next step.
