Reaction Steps
A mixture comprising 30.0 g of (tetrahydro-3-furanyl)methyl tosylate, 23.0 g of potassium phthalimide and 150 ml of DMF was stirred at 80° C. for 8 hours. Water was poured into the reaction mixture, and crystals precipitated out was separated by filtration to obtain 27.0 g of N-{(tetrahydro-3-furanyl)methyl}phthalimide.
