실험 절차

To a stirred solution of 4-biphenylsulfonamide (Greenlee, W. J.; Walsh, T. F.; et al. Eur. Pat. Appl., EP 617001 (1994)., 56 mg, 0.24 mmol) in DMF (3 mL) was added NaH (60% oil dispersion, 20 mg, 0.5 mmol) at room temperature. After 5 min, phenyl 2-[4-(2-ethyl-5,7-dimethyl-3H-imidazo[4,5-b]pyridin-3-yl)phenyl]ethylcarbamate (step 1, 100 mg, 0.24 mmol) was added, and the mixture was stirred for an additional 1 h. The mixture was poured into water (50 mL) and extracted with diethyl ether (2×50 mL). The combined extracts were washed with water (50 mL), brine (50 mL) and dried (MgSO4). Removal of solvent gave white oily solids. Purification by preparative TLC (ethyl acetate) gave 66 mg (50%) of the title compound as a colorless oil: MS (ESI) m/z 554 (M+H)+; 1H-NMR (CDCl3) δ 8.06 (2H, d, J=8.6 Hz), 7.13 (2H, d, J=8.6 Hz), 7.60–7.53 (2H, m), 7.48–7.36 (3H, m), 7.21 (2H, d, J=8.4 Hz), 7.12 (2H, d, J=8.3 Hz), 6.92 (1H, s), 6.11 (1H, br.t, J=5.5 Hz), 3.54 (2H, dt, J=5.9, 6.0 Hz), 2.89 (2H, d, J=6.0 Hz), 2.64 (2H, q, J=7.5 Hz), 2.66 (3H, s), 2.40 (3H, s), 1.18 (3H, t, J=7.5 Hz).
