Reaction Steps

A Wheaton vial equipped with a stir bar was charged with 4-[2-dimethylamino-1-(3-fluoro-phenyl)-ethylamino]-6-hydroxy-quinazoline-8-carboxylic acid amide, (37 mg, 0.1 mmol) Cs2CO3, (100 mg, 0.3 mmol) and dry DMF, (1 mL). The mixture was heated at 60° C. for 1 h. It was then cooled to RT and ethylbromide (11 mg, 0.1 mmol) was added a solution in DMF (0.5 mL). The mixture was left to stir overnight. After 18 h, LCMS indicated consumption of SM. The mixture was diluted with EtOAc, (30 mL) and added to water, (30 mL). The phases were separated and the aqueous was extracted with EtOAc, (30 mL) (×2). The EtOAc phase was washed with sat. LiCl, (30 mL) dried (Na2SO4) and the solvent was evaporated under reduced pressure. The material was purified by chromatography using a 4 g silica cartridge eluting with DCM-[DCM-MeOH—NH4OH (9:1:0.1)], gradient 0 to 100% cocktail. Amount obtained: 6 mg, 0.015 mmol, 15% yield.
