실험 절차

A mixture of 5-fluoro-3-(4-(methylsulfinyl)pyrimidin-2-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine, 127a, (0.052 g, 0.121 mmol) and (3R)-3-amino-4,4-dimethyl-pentanoic acid, 2a, (0.035 g, 0.242 mmol) along with Na2CO3 (0.051 g, 0.483 mmol) in a mixture of THF (0.780 mL) and acetonitrile (0.260 mL) was heated to 125° C. for 30 minutes under microwave irradiation. Then, the temperature was raised to 150° C. for a further 2.5 hours. The mixture was neutralized with aqueous 2N HCl and extracted with several portions of EtOAc. The organic solvents were evaporated in vacuo. Purification by flash chromatography (SiO2, 0-100% hexanes-EtOAc (with 10% MeOH)) provided 19 mg of the desired material (31% yield), which was used in the next step without further purification: LCMS Gradient 10-90%, 0.1% trifluoroacetic acid, 5 minutes, C18/ACN, RT=2.70 minutes (M+H) 512.00.
