実験手順

In a round-bottomed flask, 4-{3-[7-tert-butylcarbamoyl-5-(2-trimethylsilanylethoxymethyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl]-5-difluoromethoxy-indazol-1-yl}-piperidine-1-carboxylic acid tert-butyl ester (65 mg, 0.091 mmol) was dissolved in dichloromethane (0.5 ml) and trifluoroacetic acid (0.28 ml, 3.63 mmol) was added. The reaction mixture was stirred at room temperature for 2 h then concentrated. The residue was dissolved in dichloromethane (0.5 ml) and ethylenediamine (0.37 ml, 5.48 mmol) was added. The reaction was stirred at room temperature for 1 h then water and ethyl acetate were added. The resulting suspension was filtered and washed with hot water and ethyl acetate. The product collected was dried under high vacuum to provide 37 mg (80%) of 2-(5-difluoromethoxy-1-piperidin-4-yl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid tert-butylamide as an off-white powder. MS: (M+H)+=484; 1H NMR (DMSO-d6, 300 MHz): δ (ppm) 9.06 (s, 1H), 8.37 (s, 1H), 8.19 (d, J=2.3 Hz, 1H), 7.96 (d, J=9.1 Hz, 1H), 7.89 (s, 1H), 7.38 (dd, J=9.1, 2.3 Hz, 1H), 7.18 (t, J=74.8 Hz, 1H), 4.73-4.93 (m, 1H), 3.12 (d, J=12.8 Hz, 2H), 2.63-2.81 (m, 2H), 2.01-2.19 (m, 2H), 1.89-2.01 (m, 2H), 1.49 (s, 9H).
