Procedure

To a 100 mL round bottom flask, 4-amino-2-fluoro-N,N-dimethyl-benzamide (2.5 g, 0.0137 mol), 4-bromophenylisocyanate (3.3 g, 0.0164), TEA (3.9 mL, 0.0274 mol) and DCM (50 mL) was added. The reaction mixture was stirred at room temperature for 12 h. After 12 h, the precipitate was formed and was collected by filtration. The solid was washed with diethyl ether and dried to get the title compound [3.0 g, 58%]. Calculated mass: 379.0; Observed mass: 380.0 (RT: 1.46 min). This compound was directly taken to the next step.
