Procedure

Method 6—Step a A mixture of 5-Bromo-2-fluoro-benzoic acid (1.50 g, 6.85 mmol), 4-methoxy-benzene-1,2-diamine dihydrochloride (1.77 g, 8.49 mmol), HATU (2.73 g, 7.19 mmol) and TEA (2.88 mL, 20.76 mmol) in dichloromethane (20 mL) and DMF (5 mL) was stirred at room temperature overnight, then water was added (50 mL), mixture was stirred for 2 h and left standing at room temperature overnight. The precipitate obtained was filtered off and dried to afford 1.45 g of the title compound (50%).
