実験手順

To a 15-mL round-bottomed flask was added N-isopropyl-5-(3-(2-(isopropylamino)-6-((4-methoxybenzyl)oxy)pyrimidin-4-yl)-1H-indol-5-yl)-1,3,4-oxadiazol-2-amine (77 mg, 0.150 mmol) and TFA (0.3 mL, 4.04 mmol) in DCM (1 mL). The reaction was stirred at RT for 15 min and then the solvent was removed. The residue was purified with preparative HPLC (10-50% MeCN in water with 0.1% TFA in each solvent) and the fractions containing the product were combined and concentrated in vacuo to remove MeCN. The resulting mixture was extracted with CHCl3/iPrOH (4:1) and the combined organic layers were dried (MgSO4), filtered and concentrated to give 2-(isopropylamino)-6-(5-(5-(isopropylamino)-1,3,4-oxadiazol-2-yl)-1H-indol-3-yl)pyrimidin-4(3H)-one (20.0 mg, 0.051 mmol, 33.9% yield) as a light yellow solid. MS (ESI, pos. ion) m/z: 394.1 (M+1); 1H NMR (400 MHz, DMSO-d6) δ ppm 11.90 (1H, br. s.), 10.14-10.38 (1H, m), 8.75 (1H, s), 8.15 (1H, s), 7.63-7.70 (1H, m), 7.48-7.62 (2H, m), 6.23-6.40 (1H, m), 6.03 (1H, s), 4.24 (1H, dq, J=13.3, 6.5 Hz), 3.75 (1H, dq, J=13.6, 6.6 Hz), 1.29 (6H, d, J=6.5 Hz), 1.24 (6H, d, J=6.7 Hz).
