3-(Trifluoromethyl)phenyl isocyanate → HCID 45381212, compound

Participants

Reaction Steps

A solution of 3-(4-aminophenyl)-1-((S)-tetrahydrofuran-3-yl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.1 g, 0.34 mmol) in CH2Cl2 (10 mL) was cooled in an ice-water bath. To this, 3-(trifluoromethyl)phenyl isocyanate (0.047 mL, 0.34 mmol) diluted in CH2Cl2 (5 mL) was added dropwise. The reaction was allowed to warm to room temperature and left stirring for 12 hours. Reaction completion was judged by TLC and LC-MS. The reaction mixture was filtered, dried onto silica, and purified using silica gel column chromatography (50% EtOAc:Hexanes to 100% EtOAc gradient) to afford final compound AD66. ESI-MS m/z [M+H]+ found 484.4, calculated 484.2.
