Procedure
To a flask containing the product of Step 2 (2.79 g, 7.06 mmol) in DMF (71 mL) were added tert-butyldimethylsilyl chloride (1.60 g, 10.59 mmol), imidazole (0.96 g, 14.12 mmol) and DMAP (86 mg, 0.71 mmol). After two hours, the reaction was diluted with water and ethyl acetate. The organic layer was separated, dried over magnesium sulfate, filtered and concentrated in vacuo. Column chromatography on silica gel afforded N-[3-({[tert-butyl(dimethyl)silyl]oxy}methyl)-5-iodophenyl]-4-(trifluoromethyl)pyrimidin-2-amine. MS ESI calc'd. for C18H24F31N3OSi: [M+H]+ 510. found 510.
