Boscalid is an active ingredient in several fungicides marketed by the BASF. Literature approaches use multipot processes, organic solvents, and unsustainable levels of palladium catalysis. Herein is disclosed a 1-pot, 3-step route using nanomicelles in water as the reaction medium and a very low loading (700 ppm or 0.07 mol %) of costly and endangered Pd. The sequence developed involves an initial Suzuki–Miyaura cross-coupling, the product from which is not isolated. The second step relies on a carbonyl iron powder (CIP) reduction of the aryl nitro group, followed by the third and final step involving an acylation with the required 2-chloronicotinyl chloride. The overall isolated yield for these three steps is 83%.
