Abstract
Synthesis of furosemide. specifically labelled at the 2‐furanylmethyl α‐position with ^2^H or ^3^H is reported. This synthesis required reduction of N‐[(2‐furanyhethyl)amino]‐4‐chloro‐5‐(N‐acetylaminosulfonyl)benzoia acid (2) with sodium ^2^H‐ or ^3^H‐borohydride. followed by alkaline hydrolysis of the acetyl group.
