Procedure

In a manner similar to that described for the preparation of 2-(4-pyridinyl)-4-thiazolylcarbonylazide, 6.0 g of 2-(3-pyridinyl)-4-thiazolylcarboxylic acid was treated successively with NaOH, oxalyl chloride and a solution of NaN3 in water to give the 3-pyridinylazide as a pale brown solid. MS m/z: 204.5 (M−N2+H)
