Versuchsvorschrift
To 500 mL round-bottom flask was added 4-chloro-2-(methylsulfonyl)thieno[2,3-d]pyrimidine (15 g, 60 mmol), ethyl alcohol (300 mL), nitrogen gas was bubbled for 5 minutes. To this solution was added 10% palladium on activated charcoal (15 g). To the resulting mixture was bubbled hydrogen gas over night. The reaction mixture was filtered through Celite. The filtrate was concentrated to give the title compound (11.0 g). MS (ES+): 215 (M+H)+.
