反応手順

To a solution of 5-(4-chlorophenyl)furan-2-carboxylic acid (45 mg, 0.20 mmol) and 3-amino-N-cyclopropyl-4-methylbenzamide hydrochloride (prepared as described in WO 04/071440) (50 mg, 0.22 mmol) in DMF (0.5 mL) DIPEA (0.105 mL, 0.6 mmol) and the resulting mixture was stirred at rt for 1 h then at 80° C. for 1 h. The reaction was cooled to rt and water (3 mL) was added and the crude product was collected by vacuum filtration and dried under vacuum to afford 78 mg of a tan solid. The crude product was recrystallized from CH2Cl2 to afford 48 mg of a light tan solid as the title compound (Example 127). HPLC Ret. Time=3.52 min, LCMS [M+H]+ 395.23.
