Thiophosgene → 2-(3-Chlorophenyl)-2-(4-nitrophenyl)ethyl Isothiocyanate

Participants

Reaction Steps

A solution of 1.192 mmol of thiophosgene in 5 ml of methylene chloride was added to an aqueous solution of 2.71 mmol of sodium bicarbonate. Then, over the course of 15 minutes, a mixture of 1.084 mmol of 2-(3-chlorophenyl)-2-(4-nitrophenyl)ethylamine was added dropwise to this mixture. After removal of the organic phase and extraction of the aqueous phase once again with dichloromethane, the combined organic phases were washed with water and the solvent was removed by distillation under reduced pressure in a Rotavapor. The reddish oily 2-(3-chlorophenyl)-2-(4-nitrophenyl)ethyl isothiocyanate was stored in a closed vessel with exclusion of moisture in a refrigerator until processed further.
