Procedure

To a 50-mL round-bottomed flask was added ((2R)-4-(thiophen-2-ylsulfonyl)-1-(4-(1,1,1-trifluoro-2-hydroxypropan-2-yl)phenyl)piperazin-2-yl)methyl methanesulfonate (50 mg, 0.095 mmol, Intermediate B), 7-azaindole (16.76 mg, 0.142 mmol, Alfa Aesar, Ward Hill, Mass.) and cesium carbonate (62 mg, 0.19 mmol) in acetonitrile (2 mL). The reaction mixture was stirred at 80° C. for 18 h. The mixture was allowed to cool to room temperature. The reaction mixture was diluted with water (10 mL) and extracted with CH2Cl2 (2×30 mL). The organic extract was washed with saturated NaCl (10 mL) and dried over Na2SO4. The solution was filtered and concentrated in vacuo to give the crude material as a white solid. Purification by silica gel chromatography, eluting with 50% EtOAc in hexanes gave 2-(4-((S)-2-((1H-pyrrolo[2,3-b]pyridin-1-yl)methyl)-4-(thiophen-2-ylsulfonyl)piperazin-1-yl)phenyl)-1,1,1-trifluoro-2-propanol (28 mg) as a mixture of two isomers.
