Reaction Steps

A mixture of 1-(3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl)-3-(4-(2-iodoethoxy)naphthalen-1-yl)urea (J. Med. Chem., 2003, 46, 4676-4686) (400 mg, 0.704 mmol), potassium carbonate (292 mg, 2.111 mmol) and 4-nitroimidazole (88 mg, 0.774 mmol) in DMF (2.0 mL) was placed in a pre-heated oil bath at 50° C. and stirred for 16 hr. The mixture was cooled to RT, poured into water (5.0 mL) and extracted with EtOAc (5.0 mL×2). The combined organic layers were dried, filtered and evaporated and the resulting residue was subjected to column chromatography (40 g), eluting with EtOAc to give 1-(3-tert-butyl-1-p-tolyl-1H-pyrazol-5-yl)-3-(4-(2-(4-nitro-1H-imidazol-1-yl)ethoxy)naphthalen-1-yl)urea (35) as a brown solid (276 mg, 60%): m/z 554 (M+H)+ (ES+).
