Vorschrift

Copper (I) oxide (9.2 mg, 0.06 mmol) was added to (5-bromopyridin-3-yl){7-[(1R)-1-methyl-2-(tetrahydro-2H-pyran-2-yloxy)ethyl]-7H-pyrrolo[2,3-d]pyrimidin-5-yl}methanone (285 mg, 0.64 mmol) (see Preparation 26) and concentrated ammonia solution (2 mL) in 1-methyl-2-pyrrolidinone (0.5 mL). The mixture was heated in a sealed vessel at 80° C. for 17 hours. Ethyl acetate (5 mL) and water (5 mL) were added to the reaction mixture and then filtered through a glass fibre filter. The organic phase was dried over magnesium sulfate and evaporated in vacuo. The crude solid was purified by column chromatography on silica gel (gradient of EtOAc:MeOH:cNH3 100:0:0 to 95:5:0.5) to afford the title compound as a colourless oil in 70% yield, 171 mg.
