Versuchsvorschrift

A mixture of (R)-tert-butyl 3-(4-amino-6-bromo-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (9) (200 mg, 0.36 mmol), ethynyltrimethyl silane (184 mg, 1.87 mmol), Pd(PPh)3Cl2 (26 mg, 0.036 mmol), CuI (17 mg, 0.087 mmol) and TEA (0.26 mL, 1.87 mmol) in toluene (5 mL) was sealed in a microwave vile and purged with N2 three times. The resulting mixture was heated at 80° C. for 2 hr before diluted with EA (20 mL) and water (20 mL). The layers were separated. The organic phase was washed with brine, dried over Na2SO4 and concentrated under reduced pressure to give the crude product which was purified by flash chromatography (silica gel, 0 to 100% EA in PE) to afford (R)-tert-butyl 3-(4-amino-5-(4-phenoxyphenyl)-6-((trimethylsilyl)ethynyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (110). The product was then dissolved in MeOH (5 mL) and KF was added to the solution. The resulting mixture was stirred at r.t. for 30 min and then concentrated in vacuo. The residue was diluted with DCM (10 mL) and water (10 mL). The layers were separated. The organic phase was washed with brine, dried over Na2SO4 and concentrated in vacuo to afford (R)-tert-butyl 3-(4-amino-6-ethynyl-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (111) (70 mg, 39% yield) as a yellow oil. LC-MS (ESI): m/z (M+1) 496.1.
