1-Chloromethylnaphthalene → 2-(naphthalen-1-ylmethyl)-1h-isoindole-1,3(2h)-dione

Participants

Reaction Steps

To a solution of 1-chloromethyl-naphthalene (8.83 g, 50 mmol) in DMF (90 mL) was added phthalimide potassium salt (11.1 g, 60 mmol). The resultant solution was stirred at 100° C. overnight. The mixture was poured into ice-cold water and the precipitate was collected, washed with small amount of methanol and dried under vacuo to give 2-naphthalen-1-ylmethyl-isoindole-1,3-dione 52 (14.2 g, 99% yield). This material was used without further purification.
