Reaction Steps

To a solution of the 1-[4-(4,4,4-trifluorobutoxy)phenyl]piperazine product from Part B (5 g, 17 mmol) in methylene chloride (50 mL) was added triethyl amine (4 mL). The mixture was cooled to 0° C. Methane sulfonyl chloride (2.4 g, 21 mmol) in a solution of methylene chloride (10 mL) was then added dropwise. After 2 hr, the reaction was complete. The solvent was removed under reduced pressure to produce a solid residue. To this solid was added water (100 mL). The resulting mixture was filtered and washed with water, and then dried under high vacuum to produce 6 g (95% yield) of the desired compound in the form of a tan solid. Proton NMR and MS were consistent with the desired structure.
