実験手順

1,8-Diazabicyclo[5.4.0]undec-7-ene (42 mg, 0.27 mmol) is added to a suspension containing 2-{4-[3-(4-tert-butoxycarbonylamino-pyridin-3-yl)-prop-2-ynyl]-2-oxo-piperazin-1-ylmethyl}-pyrrolo[3,2-c]pyridine-1-carboxylic acid tert-butyl ester (77 mg, 0.14 mmol) in anhydrous CH3CN (10 mL) and the mixture is warmed to 50° C. After 4 h, the reaction mixture is concentrated to dryness and the residue is partitioned between CH2Cl2 (50 mL) and water (50 mL) and the layers are separated. The aqueous layer is extracted twice with CH2Cl2 (25 mL) and the combined organic phase is washed with brine, dried over anhydrous Na2SO4, filtered and concentrated to provide 85 mg of the title compound as a crude solid which is used directly without further purification. 1H NMR (300 MHz, CDCl3) δ1.68 (s, 9H), 1.70 (s, 9H), 2.91 (m, 2H), 3.41 (s, 2H), 3.49 (m, 2H), 4.26 (s, 2H), 4.95 (d, J=1.1 Hz, 2H), 6.39 (d, J=0.7 Hz, 1H), 6.68 (d, J=0.7 Hz, 1H), 7.86 (m, 1H), 8.41 (m, 1H), 8.76 (br s, 1H), 8.82 (br s, 1H) ppm: MS (EI): m/z 561 (M+H).
