2-[2-[2-(2-methoxyethoxy)ethoxy]ethyl]isoindole-1,3-dione

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 1.3 g of potassium phthalimide, 2-methoxyethoxyethoxy-1-iodoethane and 5 ml of dimethylformamide were fed into a 100 ml short-neck flask provided with a reflux condenser. The resultant mixture was heated at 90° c. for 3 hours. 100 ml of ethyl acetate was added thereto and the resultant mixture was cooled to room temperature. White precipitates thus obtained were suction-filtered, and the filtrate was washed with 100 ml of water. The obtained ethyl acetate layer was dried over magnesium sulfate, and ethyl acetate was distilled off under reduced pressure to obtain the intended compound. provided with a reflux condenser White precipitates thus obtained were suction-filtered the filtrate was washed with 100 ml of water The obtained ethyl acetate layer was dried over magnesium sulfate, and ethyl acetate was distilled off under reduced pressure to obtain the intended compound
