実験手順

To a 5-mL microwave vial was added ((2R)-4-(thiophen-2-ylsulfonyl)-1-(4-(1,1,1-trifluoro-2-hydroxypropan-2-yl)phenyl)piperazin-2-yl)methyl methanesulfonate (0.200 g, 0.378 mmol, Intermediate B), potassium carbonate (0.105 g, 0.757 mmol), thiophenol (0.076 mL, 0.76 mmol, Aldrich, St. Louis, Mo.), and acetonitrile (3.0 mL). The vial was sealed and heated in an Initiator microwave reactor (Biotage AB, Inc., Uppsala, Sweden) at 140° C. for 40 min. The reaction mixture was filtered and the filtrate was concentrated. The crude product was purified by column chromatography (40 g of silica, 10 to 40% acetone in hexanes) to afford 1,1,1-trifluoro-2-(4-((2R)-2-((phenylsulfanyl)methyl)-4-(2-thiophenylsulfonyl)-1-piperazinyl)phenyl)-2-propanol (0.160 g) as a mixture of two isomers:
