Reaction Steps

A 21.5 g (0.25 mole) portion of 2-imidazolidinone in 125 ml of dimethylsulfoxide was treated with 34.5 g (0.25 mole) of K2CO3, 20 g (0.12 mole) of KI and 36.3 g (0.25 mole) of 2-fluorobenzyl chloride. The reaction mixture was heated to 105° over 0.3 hours, held at 105° for 1.8 hours, and poured into 1.51 of water all with rapid stirring. The aqueous mixture was extracted with 1.3 l of chloroform. The chloroform extract was washed with 500 ml of H2O, dried over MgSO4 overnight and filtered. The filtrate was concentrated under reduced pressure to give 42 g (86%) of a light yellow oil. The crude product was washed with 100 ml of ether to give 10 g (20%) of a white solid m.p. 72°-76°.
