Chemoselective reduction of nitrogroups in the presence of activated heteroaryl halides was achieved via catalytic hydrogenation with a commercially available sulfided platinum catalyst. The optimized conditions employ low temperature, pressure, and catalyst loading (<0.1 mol % Pt) to afford heteroaromatic amines with minimal hydrodehalogenation byproducts.
