Reaction Steps

Hydrogen chloride gas that is dried for 5 hours is introduced into a suspension of 7.50 g (32.4 mmol) of 2-(3-bromo-4-methoxy-phenyl)-ethanol, 4.90 g (32.4 mmol) of 4-nitro-benzaldehyde and 4.39 g (32.4 mmol) of freshly melted zinc chloride in anhydrous benzene (96 ml). The reaction mixture is then diluted with ethyl acetate and washed neutral with water. After drying and concentration by evaporation, the solid residue is recrystallized from ethyl acetate (25 ml). 7.91 g (67%) of 6-bromo-7-methoxy-l-(4-nitrophenyl)-isochroman, melting point 144-147° C., is obtained.
