Procedure

A solution of N2-(4-aminophenyl)-N4-(3-cyclopropyl-1H-pyrazol-5-yl)pyrimidine-2,4-diamine (0.011 g, 0.035 mmol; Shokat Lab: A. Statsyuk) in CH2Cl2 (10 mL) was cooled in an ice-water bath. To this 3-(trifluoromethyl)benzoyl chloride (0.005 mL, 0.036 mmol) diluted in CH2Cl2 (5 mL) was added drop wise. The reaction was allowed to warm and was left stirring for 1 hour. The reaction proceeded until completion as judged by TLC and LC-MS. The reaction mixture 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 AD74. ESI-MS m/z[M+H]+. Found 480.5. Calculated 480.2.
