1-(2-Chloro-4-fluorophenyl)-2-(4-hydroxyphenyl)-3-methyl-5-piperidin-1-yl-1,5,6,7-tetrahydropyrrolo[3,2-c]pyridin-4-one (0.223 g, 0.49 mmol) was co-concentrated with pyridine twice and put under nitrogen. Pyridine (2.5 ml) was added and the reaction mixture cooled to 0° C. with an ice-bath followed by addition of 3,3,3-trifluoropropane-1-sulfonyl chloride (0.153 g, 0.78 mmol). The reaction mixture was stirred at 0° C. for 3 h adding more 3,3,3-trifluoropropane-1-sulfonyl chloride (0.171 g, 0.87 mmol) after 1 h 10 min. The ice bath was removed and the reaction mixture evaporated. The crude product was purified by hplc to yield the product as a beige solid after freeze-drying (0.19 g, 63%).
