Sodium Bicarbonate → tert-butyl 4-(4-(5-fluoro-2-methoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-6-yl)piperidine-1-carboxylate

Temperatur

100 °C

To a solution of Example 1C (200 mg, 0.6 mmol) in N,N-dimethylformamide (8 mL), was added a solution of sodium bicarbonate (0.118 g, 1.404 mmol) in 0.5 mL water followed by 5-fluoro-2-methoxyphenylboronic acid (204 mg, 1.2 mmol). The mixture was degassed with nitrogen and [1,1′-bis(di tert butyl phosphino)ferrocene]palladium(II) dichloride (21 mg, 0.033 mmol) was added. The mixture was heated under microwave conditions (Biotage Initiator) at 100° C. for 1 hour. The mixture was diluted with ethyl acetate and filtered through diatomaceous earth. The organic layer was washed with water and brine, dried over sodium sulfate, filtered, concentrated and purified by column chromatography (silica gel, 40% ethyl acetate-hexane) to afford the title compound. LCMS: 427.21 (M+1)+.
