Procedure

To a stirred solution of 2-bromothiazole-5-carboxylic acid (241 mg, 1.16 mmol) and N,N-diisopropylethylamine (409 mg, 552 μL, 3.16 mmol) in methylene chloride was added (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (BOP) (559 mg, 1.26 mmol). After 15 min., 3-(aminomethyl)-7-chloro-1-phenylquinolin-4(1H)-one (intermediate D) (300 mg, 1.05 mmol) was added. The reaction mixture was stirred at room temperature. The mixture was diluted with CH2Cl2 and washed with water followed by 1N aqueous HCl and finally saturated aqueous sodium carbonate solution. The organic layer was dried (Na2SO4), filtered and concentrated. The product 2-bromo-thiazole-5-carboxylic acid (7-chloro-4-oxo-1-phenyl-1,4-dihydro-quinolin-3-ylmethyl)-amide (464 mg, 93%) was obtained without further purification.
