Ammonia → (4-Amino-2-chloro-pyrimidin-5-yl)-[3-(tert-butyl-dimethyl-silanyloxy)-5,6-difluoro-2-methoxy-phenyl]-methanone

Participants

Reaction Steps

Ammonia gas was bubbled through a solution of [3-(tert-butyl-dimethyl-silanyloxy)-5,6-difluoro-2-methoxy-phenyl]-(2,4-dichloro-pyrimidin-5-yl)-methanone (900 mg, 2.003 mmol, Example 268) in toluene (10 mL) for about 30 minutes. The reaction mixture was concentrated to dryness to give (4-amino-2-chloro-pyrimidin-5-yl)-[3-(tert-butyl-dimethyl-silanyloxy)-5,6-difluoro-2-methoxy-phenyl]-methanone (1.02 g, yellow gum). The crude product was used without further purification.
