Procedure

A sealable vial was charged with ((2R)-4-(2-thiophenylsulfonyl)-1-(4-(2,2,2-trifluoro-1-hydroxy-1-methylethyl)phenyl)-2-piperazinyl)methyl methanesulfonate (100 mg, 0.189 mmol, Intermediate B), 3-ethylmorpholine (43.6 mg, 0.378 mmol, ChemBridge Corporation, San Diego, Calif.), potassium carbonate (52.3 mg, 0.378 mmol), and 4 mL of MeCN. The vial was sealed and heated to 150° C. for 90 min. Afterwards, the reaction mixture was filtered and the filtrate was concentrated. The crude material was purified via preparatory TLC using 5% MeOH in CH2Cl2 eluent to yield 2-(4-((2S)-2-((3-ethyl-4-morpholinyl)methyl)-4-(2-thiophenylsulfonyl)-1-piperazinyl)phenyl)-1,1,1-trifluoro-2-propanol (33 mg) as a mixture of four isomers.
