Procedure

8-Chloro-4-hydroxy-7-methoxy-quinoline-2-carboxylic acid (115 mg, 0.45 mmol) and ammoniumchloride (36 mg, 0.68 mmol) were dissolved in DMF (4 mL). HATU (342 mg, 0.9 mmol) and NMM (159 mg, 1.58 mmol) were added and the mixture was stirred at r.t. overnight. An additional amount of ammoniumchloride (72 mg, 13.5 mmol) was added and heated to 53° C. for 18 h. The reaction mixture was cooled to r.t. and concentrated to give 8-chloro-4-hydroxy-7-methoxy-quinoline-2-carboxylic acid amide as a yellow solid.
