Versuchsvorschrift

A mixture of 1-(5-(5-chloro-2-(1-methyl-1H-pyrazol-4-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridin-4-yl)thiazol-2-yl)cyclobutanamine (40 mg, 0.074 mmol) (Example 121A) in anhydrous tetrahydrofuran (1 mL) was treated with trimethylsilyl isocyanate (0.049 ml, 0.371 mmol), and the reaction mixture was heated to 70° C. for 5 hours. Additional trimethylsilyl isocyanate (0.025 ml, 0.185 mmol) was added, and the reaction solution was heated for 16 hours at 70° C. The reaction was cooled, diluted with water, and extracted with dichloromethane. The organic extracts were combined and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel, eluting with 5% methanol in dichloromethane, to provide the title compound. MS ESI(+) m/z 582.3 [M+H]+.
