Pyridine → HCID 54021124, compound

Participants

Reaction Steps

Trifluoroacetic anhydride (3.15 g, 15 mmol) was added to a mixture of 2-(4-chlorophenoxymethyl)-α-methoxyiminophenylacetamide (1.19 g, 6 mmol) and pyridine (12 ml) under ice-cooling over 20 minutes, and the mixture was stirred at room temperature for 2 hours. After completion of the reaction, ether (150 ml) was added, and the mixture was washed with 1N hydrochloric acid (150 ml), water (100 ml) and saturated aqueous sodium bicarbonate solution (100 ml). The ether layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography (ethyl acetate/n-hexane) to give 2-(4-chlorophenoxymethyl)-α-methoxyiminophenylacetonitrile (1.57 g, 87.0%) as colorless crystals.
