Abstract Procedures are reported to prepare the tert ‐butyl esters of 2‐aminonicotinic acid, 4‐aminonicotinic acid, 5‐aminonicotinic acid, and 6‐aminonicotinic acid from 2‐chloronicotinic acid, 4‐chloronicotinic acid, 5‐bromonicotinic acid, and 6‐chloronicotinic acid, respectively, without need for purification of intermediates.
