Versuchsvorschrift

The 7-benzenesulfonyl-5-methyl-4-piperazin-1-yl-7H-pyrrolo[2,3-d]pyrimidine bis-hydrochloride (200 mg, 0.465 mmol) and 3-tert-butoxycarbonylamino-2-(4-chlorophenyl)-propionic acid (146 mg, 0.488 mmol) were dissolved/suspended in 2.0 mL of DMF at room temperature and treated with TEA (259 μL, 1.86 mmol). The HBTU (194 mg, 0.511 mmol) was added in one sum, and the reaction was allowed to stir overnight at room temperature to completion. The reaction was partitioned between ethyl acetate and diluted NaHCO3 solution. The aqueous was extracted with ethyl acetate, and the organics were combined. The organic was washed with water, then brine, separated, dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by chromatography (silica gel eluted with 70:30 ethyl acetate:hexanes) to afford the pure [3-[4-(7-benzenesulfonyl-5-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-piperazin-1-yl]-2-(4-chlorophenyl)-3-oxo-propyl]-carbamic acid tert-butyl ester as colorless gel (295 mg, 99%). 1H NMR (CDCl3, 400 MHz) δ 8.44 (s, 1H), 8.16 (d, J=8.4 Hz, 2H), 7.59 (t, J=7.2 Hz, 1H), 7.49 (appt, J=7.6 Hz, 2H), 7.31 (m, 3H), 7.20 (d, J=8.0 Hz, 2H), 5.12 (m, 1H), 4.09 (m, 1H), 3.92 (m, 1H), 3.60 (m, 1H), 3.56-3.46 (m, 4H), 3.38 (d, J=10.4 Hz, 2H), 3.32 (m, 1H), 2.90 (m, 1H), 2.29 (s, 3H), 1.41 (s, 9H). LCMS (APCI+) m/z 639 [M+H]+; Rt=3.70 min.
