Reaction Steps

In a reaction vessel, 7H-pyrrolo[2,3-d]pyrimidin-4-ol (37, 855 mg, 6.33 mmol) is combined with (2,4-difluoro-3-formyl-phenyl)-carbamic acid benzyl ester (33, 2.03 g, 6.96 mmol) and potassium hydroxide (1.06 g, 19.0 mmol) and 5 mL of methanol is added. The resulting solution is stirred at 50° C. for 2 days. The reaction is diluted with 1N hydrochloric acid and extracted with ethyl acetate, and the resulting solids collected by filtration and dried under vacuum. The organic layer is separated from the filtrate and the aqueous layer extracted twice more with ethyl acetate. The organic layers are combined and washed with water, brine, dried with magnesium sulfate and filtered. The filtrate is concentrated under vacuum and the resulting material is suspended in acetonitrile and sonicated for 1 hour. The solid is collected by filtration and dried under vacuum, then combined with the first solid collected to provide the desired compound (38, 2.05 g). MS (ESI) [M−H+]−=349.0.
