Triethylamine → HCID 53469612, compound

Participants

Reaction Steps

CF3(CF2)5(CH2)2SO2Cl (10 g), 3-chloropropyl amine hydrochloride (4.1 g), and 1,2-dimethoxyethane (20 g) solvent were added to the round bottom flask equipped with mechanical stirring under nitrogen. Solution of triethylamine (4.5 g) in 1,2-dimethoxyethane (10 g) solvent was added dropwise during 30 min at 20-30° C. at 250 rpm. Stirred for 12 h after the addition is completed. The reaction was monitored by GC to ensure the complete conversion 1. The final reaction mixture with pH of about 5 was filtered from solids through 2 mm layer of CELITE 545. The solids were washed with 1,2-dimethoxyethane (7 g) and combined filtrate was evaporated in vacuum to obtain 11.0 g of CF3(CF2)5(CH2)2SO2NH(CH2)3Cl. The product was additionally dissolved in hot toluene (8 g) and washed with 15.5 mL of 1 wt % HCl aqueous solution to remove traces of NH2(CH2)3Cl.
