Chloroform → HCID 21951121, 화합물

To a solution of 2-((2-amino-2-methylpropyl)amino)ethanol (12 g, 91 mmol) in 90 mL of acetone was added chloroform (10.9 mL, 136 mmol) and the solution was cooled to 0° C. with an external ice bath. A solution of NaOH (50% by weight, 43.6 g, 545 mmol) was added slowly to the cold solution over several minutes and the resultant solution was stirred at 0° C. for 2 hours then allowed to warm to room temperature and stirred for an additional 18 hr. The crude reaction mixture was filtered to remove solids, washing with acetone, and the solution was concentrated to 20 g of a clear oil. A portion of the crude material was purified by a bulb-to-bulb distillation under reduced pressure to give 1.45 g of a clear oil, which was used directly in the next step without further purification.
