実験手順

To a solution of 5-(6-(1-(cyclopropylmethyl)-1H-1,2,3-triazol-4-yl)-3H-imidazo-[4,5-b]pyridin-3-yl)-2′,4′-difluoro-[1,1′-biphenyl]-3-amine (50 mg, 0.11 mmol) in DMF was added cyclopropanecarboxylic acid (11 mg, 0.13, mmol, 1.2 eq.) followed by HATU (91 mg, 0.24 mmol, 2.0 eq.) and DIPEA (43 mg, 0.33 mmol, 3.0 eq). The mixture was stirred for 16 h and quenched extracted as in Example 1(d). The solvent was distilled off to afford the crude residue which was purified by column chromatography to give the product in 51% yield (25 mg). 1H NMR (300 MHz, DMSO): δ 10.6 (s, 1H) 8.99 (d, 2H), 8.88 (d, 1H), 8.62 (d, 1H), 8.31 (d, 1H), 7.92 (d, 1H), 7.76-7.71 (m, 2H), 7.47-7.40 (m, 1H), 7.29-7.24 (m, 1H), 4.33-4.30 (d, 2H), 3.64-3.62 (m, 2H), 3.12-3.09 (m, 2H), 1.87-1.83 (m, 1H), 0.63-0.61 (t, 2H), 0.49-0.48 (t, 2H); LC-MS (ESI): Calculated mass: 511.5; Observed mass: 511.8 [M+H]+ (rt: 1.63 min).
