Procedure

To a solution of 4-iodo-3-methylaniline (200 mg, 0.86 mmol) in benzene (5 mL) in a sealable tube was added 1-isocyanato-3-(trifluoromethyl)benzene (0.133 mL, 0.94 mL; “E” is an electrophilic group disussed in scheme 3, and here is an isocyanate). The tube was sealed and heated at 90° C. for 4 h. The mixture was allowed to cool to room temperature before filtering. The off white solid was washed with additional benzene (10 mL) and used without further purification.
