Hydrochloric Acid → 4-Benzyloxy-2-iodo-5-methoxybenzonitrile

Participants

Reaction Steps

To a mixture of 4-benzyloxy-2-iodo-5-methoxybenzaldehyde oxime (reference example 2-1)(20.8 g), triethylamine (22.7 mL) and tetrahydrofuran (181 mL) was added trifluoroacetic anhydride (23 mL) under ice-bath cooling. After stirring at room temperature for an hour, 2 mol/L hydrochloric acid and ethyl acetate were added to the mixture. The organic layer was washed with brine, and dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was triturated with methanol to give the title compound (10.25 g).
