Reaction Steps

NaH (1.94 g, 60%) is added to the solution of ethyl acetoacetate (6.02 g) in THF (100 ml) at 0° C. under nitrogen atmosphere. The reaction mixture is stirred for 15 minutes at the temperature and 3-nitrobenzylbromide (10 g) is added. The reaction mixture is stirred at room temperature overnight. The reaction mixture is poured into saturated NH4Cl eq. and extracted with EtOAc twice. The combined organic extract is washed with brine and dried over MgSO4. Concentration under reduced pressure gives the residue which is purified over column chromatography to afford ethyl 2-(3-nitrobenzyl)-acetoacetate (12 g).
