Triethylamine → 2,2,2-Trifluoroethoxybenzamide

Participants

Reaction Steps

Ethyleneimine (2.9 g., 0.068 mole), triethylamine (6.8 g., 0.068 mole) and diethyl ether (250 ml.) are cooled to 0° C. and stirred while adding 2,5-di-(2,2,2-trifluoroethoxy)benzoyl chloride (22.8 g., 0.068 mole). The mixture is allowed to warm to room temperature and filtered. The filtrate is treated with 6.6 N isopropanol-hydrochloric acid mixture and filtered and the solvent evaporated in vacuo to give N-(2-chloroethyl)-2,5-di-(2,2,2-trifluoroethoxy-benzamide, m.p. 87°-88.5° C.
