실험 절차

To a suspension of 3-bromo-1H-pyrrolo[3,2-b]pyridine-6-carboxylic acid hydrochloride (2.75 g, 9.91 mmol) and 2-tert-butyl-4,6-dihydrospiro[indazole-5,4′-piperidin]-7(2H)-one hydrochloride salt (2.95 g, 9.91 mmol) in dichloromethane (30 mL) was added triethylamine (5.52 mL, 39.6 mmol). N,N-dimethylformamide (5 mL) was then added, followed by 1-hydroxybenzotriazole (1.61 g, 11.9 mmol) and 1, (3-dimethylaminopropyl)-3-ethyl carbodiimide hydrochloride (2.28 g, 11.9 mmol). The reaction was allowed to stir at room temperature for 60 hours. The reaction was diluted with ethyl acetate and washed with saturated aqueous sodium bicarbonate and brine. The organics were dried over magnesium sulfate, filtered, and concentrated. Purification by flash column chromatography (0-10% methanol/ethyl acetate) gave the title compound (3.39 g, 71%) as a pale brown solid. +ESI (M+1+H) 486.2; 1H NMR (400 MHz, CDCl3, δ): 10.05 (br. s., 1 H), 8.57 (d, J=1.8 Hz, 1 H), 7.87 (d, J=1.8 Hz, 1 H), 7.61 (d, J=2.7 Hz, 1 H), 7.44 (s, 1 H), 3.78 (br. s., 2 H), 3.51 (br. s., 2 H), 2.81 (s, 2 H), 2.65 (s, 2 H), 1.63 (s, 13 H).
