실험 절차
To a solution of ethyl 2-cyanoacetate (10 g, 9.41 mL, 88 mmol) in EtOH (100 mL) was added 2-aminoethanol (5.40 g, 5.34 mL, 88 mmol). The mixture was refluxed for 4 h before concentration in vacuo. The mixture was purified on a 100 g Silica column eluting with 0-10% MeOH/DCM. Desired fractions were collected and concentrated to yield the desired product as a brown oil (10.2 g, 79.7 mmol, 90%). The sample was used directly in the next step without any further purification.
