Reaction Steps

Hydrogen chloride gas was passed through a solution of chroman-8-carbonitrile (370 mg, 1.736 mmol) in anhydrous ethanol (15 mL) at 0° C. After 1 h, hydrogen chloride gas was stopped and the reaction vessel was sealed with a stopper. After stirring at room temperature for 1 d, the reaction vessel was cooled to 0° C. and the stopper was removed. The solvent was evaporated in vacuo to afford chroman-8-carboximidic acid ethyl ester hydrochloride (491 mg, 88%). It was used without further purification.
