Procedure

0.40 g (1.26 mmol) of n-tetrabutylammonium fluoride trihydrate is added to a solution of 2.15 g (4.19 mmol) of 2-[4-(2-{[tert-butyldiphenylsilyl]oxy}ethyl)-4-fluoro-1-piperidyl]quinoline, obtained in step 12.5, in 20 ml of tetrahydrofuran. Stirring is continued at room temperature for 4 hours. The mixture is concentrated to dryness and the residue obtained is then purified by chromatography on silica gel, eluting with a 35/65 and then 40/60 mixture of ethyl acetate and cyclohexane.
