Pyridine → N-phenoxyphthalimide

Participants

Reaction Steps

To a 50 mL single neck RB flask wash charged with 2-hydroxy-1H-isoindole-1,3(2H)-dione (1 g, 6.13 mmol), 4 A° molecular sieves (1 g) and copper (I) chloride (0.61 g, 0.06 mmol) in DCE under open atmosphere. To the stirred reaction mixture, was added phenyl boronic acid (1.5 g, 12.2 mmol) followed by pyridine (0.53 g, 6.7 mmol) drop wise. Resulting mixture was stirred at RT for 12 h. The Reaction mixture was diluted with DCM and then filtered through celite pad. The organic layer was washed with saturated brine solution (50 mL) and dried over anhydrous Na2SO4. The solvent was removed under reduced pressure to afford off white solid. 1H NMR (300 MHz, CDCl3): δ 7.83-7.86 (q, 2H), 7.73-7.77 (m, 2H), 7.28-7.30 (m, 2H), 7.07-7.11 (m, 3H).
