실험 절차

To a solution of 1-(4-(2-aminoisonicotinoyl)naphthalen-1-yl)-3-(3-(tert-butyl)-1-(p-tolyl)-1H-pyrazol-5-yl)urea (38.0 mg, 0.073 mmol) and DIPEA (64 μL, 0.37 mmol) in dry THF (4.0 mL) under N2 at 0° C. was added 2-(2-methoxyethoxy)acetyl chloride (45.0 mg, 0.29 mmol). The reaction mixture was maintained at 0° C. for 30 min and was then warmed to RT for 1.5 hr. The reaction was quenched by the addition of a solution of NH3 (1% in MeOH, 3.0 mL) and after a further 45 min at RT was evaporated in vacuo. The residue was purified by SCX capture and release followed by flash column chromatography (SiO2, 12 g, [5% MeOH in EtOAc] in isohexane, 0-60%, gradient elution) to afford the title compound, Example 22, as a yellow solid (21 mg, 44%); Rt 2.67 min (Method 2); m/z 635 (M+H)+ (ES+); 1H NMR (400 MHz, DMSO-d6) δ: 1.29 (9H, s), 2.39 (3H, s), 3.29 (3H, s), 3.50 (2H, m), 3.66 (2H, m), 4.14 (2H, s), 6.45 (1H, s), 7.35-7.37 (3H, overlapping m), 7.46 (2H, d), 7.67-7.73 (3H, overlapping m), 8.20 (2H, m), 8.37 (1H, s), 8.49 (1H, m), 8.54 (1H, d), 9.03 (1H, s), 9.47 (1H, s), 10.24 (1H, s).
