Reaction Conditions

Reaction Steps

To a solution of 1-methoxy-3-nitro-5-(trifluoromethyl)benzene (1.0 g, 4,5 mmol) in dichloromethane (10 ml) was added pyridine hydrochloride salt (4.0 g, 35 mmol). After addition dichloromethane was removed under vacuum and the resulting solid mixture was heated at 200° C. overnight in an open reaction flask. After cooling to RT, 10% HCl (50 ml) was added and the mixture was extracted with EtOAc (3×50 ml). The combined organic layer was washed with brine (50 ml) and dried over Na2SO4. Solvent was removed under vacuum and the residue was purified by flash column chromatography on the silica gel (hexane/EtOAc=3:1) to afford the title compound as a white solid.
