実験手順

To a solution of (R)-2-(4-chlorophenylsulfonamido)-5,5,5-trifluoropentanamide (6.88 g, 20.0 mmol) and 4-(bromomethyl)-3-fluorobenzonitrile (6.43 g, 30 mmol) in DMF (35 mL) was added anhydrous Cs2CO3 (19.56 g, 60 mmol). The resulting mixture was stirred at room temperature for 45 min. and then diluted with EtOAc (200 mL), washed with water (100 mL×4) and dried over Na2SO4. The product was purified by Biotage (40+M column, 3% to 80% EtOAc in hexanes, 651 mL). The title compound was obtained as a white solid (6.50 g, 68.1% yield). 1H NMR (DMSO-d6, 400 MHz) δ 7.80-7.88 (m, 3H), 7.70-7.75 (m, 2H), 7.67 (d, 2H, J=8), 7.60 (s, 1H), 7.26 (s, 1H), 4.99 (d, 1H, J=16), 4.68 (d, 1H, J=16), 4.14 (t, 1H, J=8), 1.99-2.17 (m, 2H), 1.80-1.94(m, 1H), 1.40-1.56(m, 1H). LC/MS M+H478.14, 94%.
