Analogously to the process described in Example 126, 60 mg (0.195 mmol) of the compound of Example 83A and 48 mg (0.195 mmol) of 3-(pentafluoro-λ6-sulphanyl)benzoic acid gave 35 mg (33% of theory) of the title compound. The product obtained from the preparative HPLC purification was dissolved in a little methanol and passed through a bicarbonate cartridge (from Polymerlabs, Stratospheres SPE, PL-HCO3 MP SPE, capacity 0.9 mmol). After concentration of the eluate, the residue was dried under high vacuum.
