실험 절차

To a stirred suspension of CDI (28.8 g, 178 mmol) in DCM (250 mL) at RT, under nitrogen, was added 3-tert-butyl-1-p-tolyl-1H-pyrazol-5-amine (7) (40.7 g, 178 mmol) portion-wise over 1 hr. After 1 hr the resulting dark red solution was added dropwise, over 1 hr, to a stirred solution of N-(4-(4-aminonaphthalen-1-yloxy)pyridin-2-yl)-2-methoxyacetamide (12) (35.5 g, 99 mmol) in DCM (1 L). After 1 hr MeOH (100 mL) was added and the mixture was kept at RT for 16 hr. The reaction mixture was evaporated in vacuo and the residue was taken up into DCM (500 mL) and was washed with water and saturated aqueous NaHCO3 solution (500 mL). The organic layer was dried (MgSO4), evaporated in vacuo and the residue purified by flash column chromatography (SiO2, 800 g, 2% MeOH in DCM, isocratic elution). This product was recrystallized from ethyl acetate/heptane (800 mL of a 5:3 v/v mixture) to afford N-(4-(4-(3-(3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl)ureido)naphthalen-1-yloxy)pyridin-2-yl)-2-methoxyacetamide (1) (25.5 g, 45%) as a white powder. Found: C, 68.41; H, 5.93; N, 14.36; C33H34N6O4 requires: C, 68.49; H, 5.92; N, 14.52%.
