Reaction Steps

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 triethylamine (0.014 ml, 0.104 mmol) and dimethylcarbamoyl chloride (8.18 μl, 0.089 mmol), and the reaction mixture was heated to 70° C. for 16 hours. Additional dimethylcarbamoyl chloride (4.09 μl, 0.044 mmol) and triethylamine (0.007 ml, 0.052 mmol) were added, and reaction solution heated for another 16 hours at 70° C. The reaction was cooled, diluted with water, and extracted with dichloromethane. The extracts were combined and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel, eluting with a gradient of 2 to 5% methanol in dichloromethane, to provide the title compound. MS ESI(+) m/z 610.3 [M+H]+.
