실험 절차

4-{3-(Cyanomethyl)-3-[4-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-1-yl]azetidin-1-yl}-N-isopropylbenzamide was dissolved in dichloromethylene (5 mL). To the solution was added trifluoroacetic acid (TFA) (2.5 mL). The mixture was stirred at room temperature for 1 hour. The volatiles were removed under reduced pressure. The residue was dissolved in methanol (10 mL). To the solution was added ethylenediamine (1 mL). The mixture was stirred at room temperature for 4 hours, and was purified by RP-HPLC (pH=10) to afford the desired product (0.415 g). LCMS (M+H)+: m/z=440.1. The high purity (99.6%) of the product was obtained by re-crystallization from acetone-ether. 1H NMR (400 MHz, CDCl3): δ 9.57 (s, 1H), 8.31 (d, J=4.9 Hz, 1H), 8.15 (s, 1H), 8.11 (s, 1H), 7.70 (m, 2H), 7.39 (d, J=3.4 Hz, 1H), 7.18 (d, J=4.9 Hz, 1H), 6.70 (d, J=3.4 Hz, 1H), 6.55 (m, 2H), 5.79 (d, J=7.8 Hz, 1H), 4.47 (d, J=8.3 Hz, 2H), 4.38 (d, J=8.3 Hz, 2H), 4.27 (m, 1H), 3.45 (s, 2H), 1.25 (d, J=6.7 Hz, 6H).
