Reaction Steps

1-Methoxy-3-nitro-5-trifluoromethyl-benzene (10 g, Aldrich) and pyridine-HCl (41.8 g, Aldrich) were mixed together and heated neat at 210° C. in an open flask. After 2.5 h the mixture was cooled to RT and partitioned between 1N HCl and EtOAc. The EtOAc fraction was washed with 1N HCl (4×), brine (1×), dried with Na2SO4, filtered and concentrated in vacuo to form 3-nitro-5-trifluoromethyl-phenol as an off-white solid.
