Reaction Steps

A mixture of 2-(5-bromo-2, α-dihydroxybenzyl) pyridine N-oxide (2.50 g), activated manganese dioxide (12.5 g) and chloroform (60 ml) was stirred for 16 hours at room temperature. The manganese dioxide was filtered off, and the filtrate was concentrated. The concentrate was recrystallized from ethyl acetate to give 2-(5-bromo-2-hydroxybenzoyl)pyridine N-oxide (1.26 g, m.p. 160°-162° C.), whose spectrum data are shown below.
