Tetrahydrofuran → (R)-5-(2-(2-aminopyrimidin-5-yl)ethynyl)-2-fluoro-N-(2-(3-hydroxypiperidin-1-yl)-5-(trifluoromethyl)phenyl)benzamide

Participants

Reaction Steps

To a yellow solution of (R)-5-(2-(2-aminopyrimidin-5-yl)ethynyl)-N-(2-(3-(tert-butyldimethylsilyloxy)piperidin-1-yl)-5-(trifluoromethyl)phenyl)-2-fluorobenzamide (0.162 g, 0.264 mmol) was added tetrabutylammonium fluoride, 1.0 M in THF (0.688 ml, 2.38 mmol). The reaction was allowed to stir for 6 h, at which point it was found by TLC analysis to be complete. The reaction was diluted with EtOAc and washed once with brine. The organic layer was dried over anhydrous sodium sulfate and concentrated in vacuo to give a yellow oil, which was purified by silica gel chrmatography, 0-10% MeOH/MC to give (R)-5-(2-(2-aminopyrimidin-5-yl)ethynyl)-2-fluoro-N-(2-(3-hydroxypiperidin-1-yl)-5-(trifluoromethyl)phenyl)benzamide as an off-white solid. MS m/z=500 [M+H]+. Calc'd for C25H21F4N5O2: 499.
