Procedure
A cold solution (0° C.) of 4-methoxybenzonitrile (1.29 g, 9.59 mmol) in ethanol (30 mL) was saturated with dry HCl(g). The mixture was then stirred at room temperature for 2 days, after which FT-IR showed complete disappearance of the nitrile. The solution was concentrated to dryness, and further dried in vacuo. The ethyl 4-methoxybenzimidate hydrochloride thus obtained was used in the synthesis of compounds 152, 153 and 154.
