Reaction Steps

In 450 ml of anhydrous methanol, was suspended 44.0 g of methyl 5-cyanosalicylate. While being cooled in ice and stirred, the suspension was saturated with dried gaseous hydrogen chloride. The suspension was further stirred for 2 days at room temperature, then the resulting solution was concentrated to about 200 ml at a low temperature under reduced pressure, and admixed with ethyl acetate to precipitate colorless crystals. The crystals were collected by filtration and dried to obtain 41.0 g of methyl 5-methoxyiminomethylsalicylate hydrochloride.
