7-Chloro-3-(4-methoxyphenoxy)isoquinoline (3.50 g) was refluxed in a mixture of acetic acid (25 ml) and a solution of hydrogen bromide (25 ml, 48%) for 3 hrs. The mixture was cooled, poured into water, neutralized with sodium carbonate and extracted with ethyl acetate. The extract was washed thoroughly with water, dried (MgSO4) and evaporated to give 4-[(7-chloroisoquinolin-3-yl)oxy]phenol (3.02 g) as brown solid, mp 190° C.
