Reaction Steps

A 5-mL microwave vial was charged with ((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) diisopropylamine (0.077 g, 0.757 mmol), potassium carbonate (0.105 g, 0.757 mmol), in 3 mL of MeCN. The vial was sealed and heated in an Initiator microwave reactor (Biotage AB, Inc., Uppsala, Sweden) at 140° C. for 30 min. The reaction mixture was filtered and the filtrate was concentrated. The crude product was purified by column chromatography on silica gel (40 g of silica gel, 10 to 40% EtOAc in hexanes) to afford 2-(4-((2S)-2-((bis(1-methylethyl)amino)methyl)-4-(2-thiophenylsulfonyl)-1-piperazinyl)phenyl)-1,1,1-trifluoro-2-propanol (0.130 g) as
