Procedure

A mixture of ethyl 4-(3-aminophenyl)-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylate (300 mg, 1.06 mmol), 2-((tert-butoxycarbonylamino)methyl)acrylic acid (321 mg, 1.60 mmol), HATU (606 mg, 1.59 mmol) and DIPEA (371 μL, 2.13 mmol) in DMF (5.0 mL) was stirred at room temperature for 3 hours. The resulting mixture was diluted with ethyl acetate (15 mL) and washed with saturated aqueous bicarbonate, brine, dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by reverse phase HPLC using an acetonitrile gradient in water with 0.1% TFA modifier to give ethyl 4-(3-(2-((tert-butoxycarbonylamino)methyl)acrylamido)phenyl)-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylate. LRMS (ESI) calc'd for C24H28N5O5 [M+H]+: 466, found 466.
