Participants

Reaction Steps

To a solution of 2-(4-(5-chloro-4-(2-(1-(methoxymethoxy)cyclobutyl)thiazol-5-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridin-2-yl)-1H-pyrazol-1-yl)acetaldehyde (14C) (300 mg, 0.490 mmol) in tetrahydrofuran (3.267 mL) was added sequentially acetic acid (0.056 mL, 0.980 mmol), sodium sulfate (139 mg, 0.980 mmol) and dimethylamine (0.368 mL, 0.735 mmol). The reaction was stirred for 0.5 hours at ambient temperature, and sodium triacetoxyborohydride (208 mg, 0.980 mmol) was added in a single portion. The reaction was stirred overnight and then quenched by the addition of saturated aqueous sodium bicarbonate and ethyl acetate. The layers were separated, and the aqueous layer was extracted with addition ethyl acetate (2×). The combined organics were dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give the title compound, which was used in the next step without further purification. MS ESI(+) m/z 641.2 [M+H]+.
