Participants

Reaction Steps

3-[4-Amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl]cyclopentanol (50 mg, 0.129 mmol) and N-tert-butoxycarbonyl glycine (34 mg, 0.194 mmol) was mixed in N,N-dimethylformamide (1 ml). 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (31 mg, 0.155 mmol) and 4-dimethylamino pyridine (16 mg, 0.129 mmol) was added. The resulting mixture was stirred under nitrogen at ambient temperature for 24 hours. The reaction mixture was poured into ice water and extracted with ethyl acetate. The organic extracts were washed with brine, dried (MgSO4), filtered and evaporated. The solid was purified by flash column chromatography on silica using ethyl acetate as the mobile phase to give 3-[4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl]cyclopentyl 2-[(tert-butoxycarbonyl)amino]acetate. The structure was confirmed by 1H NMR.
