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, 0.112 mmol) in DCM was added pyridine (26 mg, 0.33 mmol, 3.0 eq.) and ethanesulfonyl chloride (17 mg, 0.135 mmol, 1.2 eq.). After completion of the reaction the solvent was distilled off and the crude product was purified by preparative HPLC to give the product in 33% yield (20 mg). 1H NMR (300 MHz, DMSO): δ 10.3 (s, 1H) 9.02-8.99 (m, 2H), 8.81 (d, 1H), 8.63-8.61 (d, 1H) 7.95 (d, 1H), 7.77-7.69 (m, 2H), 7.49-7.42 (m, 2H), 7.31-7.25 (d, 1H), 4.33 (d, 2H), 3.42-3.26 (m, 2H), 1.34-1.24 (t, 3H), 0.63-0.60 (t, 2H), 0.49-0.48 (t, 2H); LC-MS (ESI): Calculated mass: 535.5; Observed mass: 535.8 [M+H]+ (rt: 0.1.33 min).
