Reaction Steps

Hydrogen chloride gas was passed through a solution of 4-ethoxy-2-isopropoxy-benzonitrile (0.30 g, 1.46 mmol) in absolute ethanol (100 mL) in a pressure tube for 45 min at 0° C. The tube was sealed and stirred at room temperature for 4 d. The pressure was released only after the tube is cooled to 0° C. Evaporation of the solvents and trituration of the residue in diethyl ether gave ethyl 4-ethoxy-2-isopropoxy-benzimidate hydrochloride which was used without further purification.
