실험 절차

4.72 g (19.8 mmol) of diethyl 2-bromomalonate are introduced into 30 ml of acetonitrile. Then 3.82 g (27.7 mmol) of potassium carbonate and 2.46 g (21.7 mmol) of 8-oxa-3-azabicyclo[3.2.1]octane from step 4 are added. The suspension is stirred at 50° C. overnight. This is followed by filtration with suction and evaporation of the filtrate to dryness in a rotary evaporator. The residue is employed without further purification in the next stage.
