Benzyl Bromide → 2,2'-((Phenylmethyl)imino)bisethanol

Participants

Reaction Steps

Diisopropylethylamine (2.99 mL, 17.1 mmol) and benzyl bromide (1.36 mL, 11.4 mmol) were added to a chloroform (46 mL) solution of diethanolamine (1.80 g, 17.1 mmol), and the solution was stirred for 5 hours under heat and reflux. The reaction solution was washed with water, saturated sodium bicarbonate water, and saturated brine, dried over magnesium sulfate, and evaporated after filtration. The resulting residue was purified by silica gel column chromatography (methanol/chloroform=0/100 to 12/88) to give N-benzyldiethanolamine (1.77 g, 79.4%).
