This report presents an efficient synthesis of [ 15 N]t‐butylamine hydrochloride. Acylation of [ 15 N]ammonia with pivaloyl chloride provided [ 15 N]pivalamide, this was converted to benzyl [ 15 N]N‐t‐butylcarbamate through a Hofmann rearrangement. Hydrogenolysis of benzyl [ 15 N]N‐t‐buylcarbamate and acidification afforded [ 15 N]t‐butylamine hydrochloride in an overall yield of 79.2% in four steps. Copyright © 2010 John Wiley & Sons, Ltd.
