Reaction Steps

A solution of 9.74 g (0.0359 mole) of ethyl 2-(2-methoxyphenylamino)benzoate in 50 ml of methylene dichloride was cooled to -78° C. and 114 ml of boron tribromide (1M in methylene dichloride) was added dropwise over a period of 20 minutes. The reaction mixture was stirred at -78° C. for three hours, then at -40° C. for one hour and finally kept in a refrigerator at -4° C. overnight. Ether (50 ml) was added and the mixture poured into ice-water and ether. The ether solution was separated, dried over anhydrous magnesium sulfate and concentrated. The residue was recrystallized from acetonitrile to give 5.3 g of ethyl 2-(2-hydroxyphenylamino)benzoate, m.p. 105°-106° C.
