Reaction Steps

A solution of 54.01 g (0.226 mole) of 4-(2-bromoethoxy) indan and 41.81 g (0.226 mole) of potassium phthalimide in 1200 ml of dimethylformamide was stirred overnight at 85° C. The reaction was filtered and dimethylformamide removed in vacuo in a rotary evaporator to give a white solid. The solid was dissolved in methylene chloride and extracted with water. Methylene chloride was evaporated to give a light brown solid. The solid was triturated with diethyl ether to give 59.3 g light brown solid. A portion of the solid was recrystallized from methylene chloride-ethanol-diethyl ether to give a white crystalline solid, m.p. 128.5°-132.0° C.
