Versuchsvorschrift

8.51 g (61.57 mmol) of potassium carbonate are added to a solution of 10.0 g (58.64 mmol) of 4-hydroxy-2-nitrobenzaldehyde in 70 ml of DMF. The solution is briefly stirred, then 10.53 g (61.57 mmol) of benzyl bromide are added and the reaction mixture is stirred at room temperature for 3 h. The resulting solid is then filtered off, 250 ml of water are added to the filtrate and the aqueous phase is extracted 3× with ethyl acetate. The organic phase is washed twice with water, dried over sodium sulphate, concentrated in vacuo and the residue is dried. 15.0 g (99%) of 4-benzyloxy-2-nitrobenzaldehyde are obtained as a yellow solid.
