Steps:

Synthesis of the compounds 2 and 4; general procedure

General procedure: Bis(trichloromethyl) carbonate (BTC) (5.0 mmol 1.48 g) was dissolved in DCM (30 mL). The aromatic primary aniline (10.0 mmol) in DCM (20 mL) was added dropwise to the above solution at 0 °C over 30 min. After the aryl primary aniline reacted completely (monitoredby GC), triethylamine (25.0 mmol, 2.53g) was added dropwise to the above mixture and stirred for 1-2 h at room temperature (monitored by TLC). The solid was obtained after distillation of DCM, washing by water (2×10 mL), and filtration.
