Reaction Steps

A solution of 4-bromo-benzonitrile (58 mmol) in ethanol (200 mL) at 0° C. was bubbled through with HCl gas for 30 min and the resulting solution was stirred from 0° C. to room temperature over the weekend. After the reaction mixture was concentrated in vacuo, the residue was suspended in ether and the solid was filtered to give of 4-bromo-benzimidic acid ethyl ester as HCl salt (47 mmol).
