실험 절차

To a stirred solution of 3-pyridinesulfonamide (Rafik, Karaman; et al., J. Am. Chem. Soc., 1992, 114, 4889, 120 mg, 0.76 mmol) in DMF (3 mL) was added NaH (60% oil dispersion, 27 mg, 0.68 mmol) at room temperature. After 10 min., phenyl 2-[4-(2-ethyl-5,7-dimethyl-3H-imidazo[4,5-b]pyridin-3-yl)phenyl]ethylcarbamate (step 1, 313 mg, 0.64 mmol) was added, and the mixture was stirred for 9 h at 80° C. The mixture was diluted with ethyl acetate (50 mL), and washed with water and brine. The organic layer was dried (Na2SO4) and concentrated. Purification by TLC developing with dichloromethane/methanol (6:1) and TLC developing with dichloromethane/methanol (10:1) gave 67 mg (19%) of the title compound as colorless solid.
