Procedure

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)benzoyl chloride (0.050 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. The reaction proceeded until completion as judged by TLC and LC-MS, was concentrated in vacuo, resuspended in 50:50 H2O—CH3CN, and purified on a C18 column in CH3CN/H2O/0.1% TFA (1-100% gradient) to afford AD67. ESI-MS m/z [M+H]+ found 469.4, calculated 469.2.
