YieldReaction ConditionsOperation in experiment
With caesium carbonate; In N,N-dimethyl-formamide; at 75℃; Step 1 : Preparation of 4-hvdroxy-3-methoxy-2-nitrobenzonitrile; 4-Hydroxy-3-methoxy-2-nitrobenzaldehyde (200 g, 1.01 mol) was dissolved in THF (2.5 L) and then ammonium hydroxide (2.5 L) was added followed by iodine (464 g, 1.8 mol). The resulting mixture was allowed to stir for 2 days at which time it was concentrated under reduced pressure. The residue was acidified with HCI (2 N) and extracted into diethyl ether. The organic layer was washed with brine and dried (sodium sulfate) and concentrated under reduced pressure. The residue was washed with diethyl ether and dried under vacuum to provide the title compound (166 g, 84%): 1H NMR (DMSO-cfe) delta: 11.91 (1 H, s), 7.67 (1 H, d), 7.20 (1 H, d), 3.88 (3H, s)
