실험 절차

Sodium hydride (60%) (0.0899 mol) was added portionwise under N2 at room temperature to a mixture of 2-hydroxybenzaldehyde (0.0818 mol) in N,N-dimethyl-formamide and the mixture was stirred under N2 for 15 minutes. 2-Chloro-3-nitro-pyridine (0.0818 mol) in N,N-dimethylformamide was added and the mixture was stirred at 100° C. for 2 hours. The mixture was poured into ice/water, extracted with diethylether and the solvent was evaporated, yielding 4.5 g (23%) of 2-[(3-nitro-2-pyridinyl)oxy]benzaldehyde (interm. 1).
