実験手順

To a solution of [4-amino-2-(1-methanesulfonyl-piperidin-4-ylamino)-pyrimidin-5-yl]-[3-(tert-butyl-dimethyl-silanyloxy)-5,6-difluoro-2-methoxy-phenyl]-methanone (675 mg, 1.181 mmol, Example 270) in tetrahydrofuran (10 mL) was added tetrabutylammonium fluoride (1.240 mL, 1.24 mmol, 1 M solution in tetrahydrofuran, Aldrich). The mixture was stirred at room temperature for 15 minutes and then concentrated to dryness. The residue was taken up in methylene chloride and washed with saturated solution of sodium bicarbonate. The organic layer was dried over anhydrous magnesium sulfate. The solids were filtered off and the filtrate was concentrated in vacuo. Purification of the crude residue by flash chromatography (Biotage system, 60 A silica gel, eluting with 65-80% ethyl acetate in hexanes then 5% methanol in ethyl acetate) yielded [4-amino-2-(1-methanesulfonyl-piperidin-4-ylamino)-pyrimidin-5-yl]-(2,3-difluoro-5-hydroxy-6-methoxy-phenyl)-methanone as white solids (315 mg, 58%). HR-MS (ES, m/z) calculated for C18H22N5O5SF2 [(M+H)+]458.1308, observed 458.1304.
