実験手順

To a stifling solution of CDI (0.21 g, 1.30 mmol) in CH2Cl2 (2 mL) was added 5-(tert-butyl)-2-(2,5-dimethylpyrrolyl)aniline (Method A4, Step 2; 0.30 g, 1.24 mmol) in one portion. The resulting mixture was stirred at room temp. for 4 h, then 4-(2-(N-methylcarbamoyl)-4-pyridyloxy)aniline (0.065 g, 0.267 mmol) was then added in one portion. The resulting mixture was heated at 36° C. overnight, then cooled to room temp. and diluted with EtOAc (5 mL). The resulting mixture was sequentially washed with water (15 mL) and a 1N HCl solution (15 mL), dried (MgSO4), and filtered through a pad of silica gel (50 g) to afford N-(5-(tert-butyl)-2-(2,5-dimethylpyrrolyl)phenyl)-N′-(4-(2-(N-methylcarbamoyl)-4-pyridyloxy)phenyl)urea as a yellowish solid (0.033 g, 24%): TLC (40% EtOAc/60% hexane) Rf 0.24; 1H NMR (acetone-d6) δ 1.37 (s, 9H), 1.89 (s, 6H), 2.89 (d, J=4.8 Hz, 3H), 5.83 (s, 2H), 6.87-7.20 (m, 6H), 7.17 (dd, 1H), 7.51-7.58 (m, 3H), 8.43 (d, J=5.4 Hz, 1H), 8.57 (d, J=2.1 Hz, 1H), 8.80 (br s, 1H); HPLC ES-MS 512 ((M+H)+, 100%).
