Versuchsvorschrift

To a stirred solution of 2-ethyl-5,7-dimethyl-3-(4-{2-[({[(4-methylphenyl)sulfonyl]amino}carbonyl)amino]ethyl}phenyl)-3H-imidazo[4,5-b]pyridine (Example 1, 200 mg, 0.41 mmol) in THF (10 mL) was added dropwise a solution of lithium diisopropylamide (LDA) (2.0 N in heptane/hexane/ethylbenzene, 0.8 mL, 1.6 mmol) with ice-cooling over a period of 10 min. After completion of the addition, the stirring was continued for an additional 20 min at the same temperature. To the resulting mixture was added dropwise Mel (0.5 mL) at 0° C., and stirred at room temperature for 15 h. The mixture was poured into a solution of phosphate buffer (100 mL) and extracted with dichloromethane (100 mL). The organic layer was washed with brine (50 mL), dried (Na2SO4), and concentrated. The residue was purified by flash chromatography on silica gel eluting with dichloromethane/methanol (10:1) to give 10 mg (5%) of the title compound as a colorless oil: 1H-NMR (CDCl3) δ 7.64 (2H, d, J=8.3 Hz), 7.53-7.25 (7H, m), 6.89 (1H, s), 3.65-3.55 (2H, m), 3.14 (3H, s), 2.96 (2H, t, J=6.7 Hz), 2.82 (2H, q, J=7.6 Hz), 2.66 (3H, s), 2.50 (3H, s), 2.40 (3H, s), 1.25 (3H, t, J=7.6 Hz).
