Procedure

To a suspension of potassium t-butoxide (17 mg, 0.151 mmol) in THF (2 mL) was added 1-methylpiperidin-4-ol (15 mg, 0.130 mmol). The mixture was allowed to stir at rt for 15 min, at which time 2-fluoro-N-(4-methyl-3-(((2-(phenylamino)-5-pyrimidinyl)amino)carbonyl)phenyl)-5-(trifluoromethyl)benzamide 40 (55 mg, 0.108 mmol) was added. The reaction mixture was stirred at room temperature for 24 h, at which time the LCMS showed complete conversion. The reaction mixture was diluted with CH2Cl2, washed with water (3×20 mL), dried over Na2SO4 and concentrated. The crude residue was taken up in MeOH/DMSO and purified on the Shimadzu reversed phase HPLC with a 15-85% gradient. Pure fractions were combined, basified with saturated sodium bicarbonate and extracted with CH2Cl2 (4×20 mL). Combined organic extracts were dried over sodium sulfate and concentrated to afford 2-methyl-5-(((2-((1-methyl-4-piperidinyl)oxy)-5-(trifluoromethyl)phenyl)carbonyl)amino)-N-(2-(phenylamino)-5-pyrimidinyl)benzamide 41. MS m/z found 605.3 [MH+]; calc. for C32H31F3N6O3=604.24.
