Reaction Steps

A solution of {[6-amino-3-cyano-2-(chloro)phenyl]methyl}(triphenyl)phosphonium bromide (Example 234A) (0.20 g, 0.39 mmol), HATU (0.157 g, 0.41 mmol), diisopropylethylamine (0.053 g, 0.41 mmol), and trifluoropropylcarboxylic acid (0.058 g, 0.41 mmol) in DMF (15 mL) was stirred at 100° C. for 24 h. After cooling to rt, the reaction was diluted with NaHCO3 (50 mL) and extracted with EtOAc (100 mL). The organic phase was washed with water and sat'd brine, dried (Na2SO4) and concentrated in vacuo. The residue was purified by flash chromatography (20-70% EtOAc-hexanes gradient) to afford the title compound as a light yellow solid: MS (ES) m/z 273 (M+1).
