Bleomycin sulfate in D 2 O was deuterated using microwave irradiation under catalyst free conditions. Following the removal of labile deuterium and purification, bleomycin A 2 with mass M + 1 to M + 7 was obtained. Successful selective uncatalyzed microwave deuterium exchange reactions on examples from the following classes of heterocycles are also described: imidazole, thiazole, indole, purine, and quinazoline. The described method was used as a test for non‐labile active protons. Copyright © 2004 John Wiley & Sons, Ltd.
