To a solution of (4-amino-phenyl)-(4-methyl-piperazine-1-yl)-methanone (10.0 g, 0.0456 mol) and TEA (4.7 g, 0.0456 mol) in DCM (150 mL) was added 4-bromophenyl isocyanate (10.9 g, 0.0547 mol). The reaction mixture was stirred at room temperature for 12 h. The white solid was obtained and was filtered and dried to afford the title compound [15.0 g, 79%]; LC-MS (ESI): Calculated mass: 416.1; Observed mass: 417.1 [M+H]+ (RT: 0.23 min).
