Optimizing Buchwald-Hartwig Coupling With 4-Bromo-2-Nitro-6-(Trifluoromethyl)Aniline
In the synthesis of triazole antifungal agents, the Buchwald-Hartwig coupling of 4-bromo-2-nitro-6-(trifluoromethyl)aniline (CAS 157026-18-1) with nitrogen nucleophiles is a critical step. This fluorinated aniline, also known as 2-amino-5-bromo-3-nitrobenzotrifluoride or 3-bromo-5-nitro-6-amino-benzotrifluoride, presents unique challenges due to its electron-deficient aromatic ring and steric hindrance from the ortho-nitro and trifluoromethyl groups. As a pharmaceutical intermediate, achieving high yields and purity requires meticulous optimization of reaction parameters. At NINGBO INNO PHARMCHEM CO.,LTD., we supply this key building block with consistent quality, enabling process chemists to streamline their synthetic routes. For those seeking a reliable source, our product serves as a seamless drop-in replacement for 4-bromo-2-nitro-6-(trifluoromethyl)aniline from major suppliers, matching technical specifications while offering cost and supply chain advantages.
