Versuchsvorschrift
Hydrogen chloride gas was passed through a solution of 3-hydroxymethyl-5-methoxymethyl-benzonitrile (720 mg, 4.063 mmol) in anhydrous ethanol (25 mL) at 0° C. After 1 h, hydrogen chloride gas was stopped and the reaction vessel was sealed with a septum. After stirring at room temperature for 1 d, the reaction vessel was cooled to 0° C. and the septum was removed. The solvent was evaporated in vacuo to afford ethyl 3-hydroxymethyl-5-methoxymethyl-benzimidate hydrochloride as a white solid (1.05 g, 100%).
