Isatoic anhydrides 1 are easily reduced with sodium borohydride to o ‐(substituted‐amino)benzyl alcohols 3 in good yield. Sequential reduction of N ‐(2‐nitrobenzyl)isatoic anhydride ( 5 ) with sodium borohydride followed by catalytic hydrogenation of the nitro group affords the naturally occurring 2‐(2′‐aminobenzylamino)‐benzyl alcohol ( 4 ) in 72% yield.
