実験手順

6-(4-Bromo-2-chloro-phenylamino)-7-chloro-3H-benzoimidazole-5-carboxylic acid methyl ester 10dd: 6-(4-Bromo-phenylamino)-7-chloro-3H-benzoimidazole-5-carboxylic acid methyl ester 8g (0.225 g, 0.591 mmol) is dissolved in DMF (2 mL) and NCS (79 mg, 0.591 mmol) is added. After the NCS is in solution concentrated HCl (0.005 mL, 0.059 mmol) is added. After 2 hours, sodium bicarbonate, water and NaHSO3 are added to the reaction mixture. Solids are filtered and washed with water and ether to give 0.141 g (57%) of clean desired product as a tan solid. MS APCI (−) m/z 414, 416 (M−, Br pattern) detected.
