Reaction Steps

A solution of N-ethylethylenediamine (10.0 g, 113.4 mmol) and ethyl trifluoroacetate (32.0 ml, 261 mmol) in the mixture of acetonitrile (110 ml) and water (2.5 ml, 139 mmol) was refluxed with stirring overnight (˜18 h). Solvents were evaporated in vacuo. Residue was re-evaporated with i-PrOH (3×100 ml). Residue was dissolved in dichloromethane (500 ml) and left overnight at room temperature. The formed crystals were filtered, washed with dichloromethane (100 ml) and dried in vacuo to provide compound M (24.6 g, 82.4 mmol) as white solid powder.
