Reaction Steps

A solution of (1S)-3,3,3-trifluoro-2-(trifluoromethyl)-1-(hydroxymethyl)propylamine (prepared according to the method of Example 13, 0.100 g, 0.4 mmol) in CH2Cl2 (1 mL) was stirred under nitrogen at 25° C. Pyridine (0.097 mL, 1.2 mmol) was added followed by 3-thiophenesulfonyl chloride (0.072 g, 0.4 mmol) in CH2Cl2 (0.5 mL), and the resulting solution stirred for 18 h at 25° C. The crude reaction mixture was loaded onto the TsOH Syntage™ samplet and after concentration was purified by the Biotage Flash™ 12 chromatography system, eluent: 30:70 EtOAc:hexanes, to obtain N-[(1S)-3,3,3-trifluoro-1-(hydroxymethyl)-2-(trifluoromethyl)propyl]thiophene-3-sulfonamide as a white solid (0.053 g, 35% yield).
