Reaction Steps
11.0 g of 7-chloro-3,4-dihydro-2(1H)-naphthalenone was boiled at reflux for 2 hours in 200 ml of benzene and 6.0 ml of pyrrolidine in the presence of 0.25 g of p-toluenesulphonic acid. The 1-(7-chloro-3,4-dihydro-2-naphthyl)pyrrolidine obtained was recrystallized from 150 ml of isopropyl ether and exhibits a melting point of 115°-116°.
