실험 절차

Methyl iodide (23.34 g, 0.165 mol) and potassium carbonate (22.73 g, 0.165 mol) are added to a solution of 5-hydroxy-2-nitrobenzaldehyde (25 g, 0.149 mol) in N,N-dimethylformamide. The reaction mixture is stirred at room temperature for 18 hours and poured into water. The resultant aqueous mixture is extracted with ethyl acetate. The organic extracts are combined, washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo to give the title product as a brown solid, mp 89°-90° C.
