N4-((trans)-3-aminocyclobutyl)-N2-(1-methyl-1H-pyrazol-4-yl)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine-2,4-diamine (87 mg, 0.2 mmol) was dissolved in DCM (5 mL). DIPEA (53 μL, 0.3 mmol) was added and the reaction was cooled to 0° C. Acryloyl chloride (16 μL, 0.2 mmol) was added via a 10 μL syringe and the reaction was allowed to stir at 0° C. for 1 hr. The reaction was concentrated and purified via flash chromatography eluting with a gradient of 1%-20% EtOH in DCM. The fractions containing the product were pooled and dried down to afford the title compound as a tan solid (confirmed to be product by LCMS). This tan solid was taken directly to the final step.
