A round bottom flask was charged with N-(4-methoxyphenyl)-4-phenylnaphthalen-1-amine (600 mg, 1844 μmol) and 6 mL 1:1 HBr (100 μl, 1844 μmol) and HOAc (106 μl, 1844 μmol). The flask was fitted with a reflux condenser and the mixture was heated at 140° C. After 1 h, LCMS showed ˜50% conversion to desired product. Heating was continued for another 5 h. Upon cooling, the mixture was brought to neutral pH by addition of 6 N NaOH and extracted with DCM. The organic portion was dried, filtered and concentrated. The crude material was purified by silica gel chromatography, 0-50% EtOAc/hex to provide 4-(4-phenylnaphthalen-1-ylamino)phenol. MS: [M+H]=312.
