実験手順
In a round-bottomed flask, 3-{3-[7-tert-butylcarbamoyl-5-(2-trimethylsilanylethoxymethyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl]-5-difluoromethoxy-indazol-1-ylmethyl}-pyrrolidine-1-carboxylic acid tert-butyl ester (134 mg, 0.188 mmol) was dissolved in dichloromethane (1 ml) and trifluoroacetic acid (0.58 ml, 7.53 mmol) was added. The reaction mixture was stirred at room temperature for 2 h then concentrated. The residue was dissolved in dichloromethane (1 ml) and ethylenediamine (0.76 ml, 11.3 mmol) was added. The light yellow solution was stirred at room temperature for 45 min then water and ethyl acetate were added. The resulting suspension was filtered and washed with hot water and ethyl acetate then dried under high vacuum to provide 33 mg (35%) of 2-(5-difluoromethoxy-1-pyrrolidin-3-ylmethyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid tert-butylamide as a light yellow powder. MS: (M+H)+=484; 1H NMR (DMSO-d6, 300 MHz): δ (ppm) 9.06 (s, 1H), 8.38 (s, 1H), 8.21 (s, 1H), 7.94 (d, J=9.1 Hz, 1H), 7.88 (s, 1H), 7.40 (d, J=9.1 Hz, 1H), 7.20 (t, J=74.8 Hz, 1H), 4.50 (d, J=6.8 Hz, 2H), 2.58-2.97 (m, 6H), 1.69-1.84 (m, 1H), 1.51 (s, 9H).
