Reaction Steps
To a stirred solution of 5-methoxy-4-(4-nitro-phenoxycarbonylamino)-2-trifluoromethyl-benzoic acid methyl ester (878 mg, 2.1 mmol) in 4.2 mL NMP at room temperature under nitrogen was added 2-amino-5-methylpyrazine (232 mg, 2.1 mmol) and the reaction heated to 85° C. After six hours the reaction was cooled to room temperature and a precipitate formed. The precipitate was triturated with EtOAc (25 mL) and the urea isolated by filtration as a tan solid (470 mg, 58%).
