Phenyl-1-naphthylamine → N-(4-methoxyphenyl)-N-phenylnaphthalen-1-amine

참여 물질

반응 단계

A mixture of N-phenylnaphthalen-1-amine (5.0 g, 22.8 mmol), 4-iodoanisole (8.0 g, 34.2 mmol), copper powder (2.89 g, 45.6 mmol), K2CO3 (12.59 g, 91.2 mmol) and 18-crown-6 (0.607 g, 2.3 mmol) in DMF (200 mL) was degassed and heated to reflux for overnight under argon. After the salt and copper were filtered off, the solution was poured into water (300 mL), and extracted with DCM (2×300 mL). The organic phase was combined and washed with brine, dried over Na2SO4, loaded on silica gel, purified by flash column (5 to 20% DCM in hexanes). The desired fraction was collected, concentrated, and recrystallized in ethyl acetate/methanol to obtain a white solid (Compound 5) (2.59 g, in 35% yield).
