A practical, safe, and scalable synthesis of the stable nitro-oxide radical catalyst ABNO was developed. This process is chromatography-free and avoids the Wolff–Kishner reduction. ¹H NMR data for this paramagnetic compound were obtained that allowed an assessment of its chemical purity. Impact sensitivity test data for solid ABNO are also reported.
