実験手順
Benzil-di-(β-bromoethyl)ketal (13.26 g) and 11.42 g of sodium 1,2,5,6-tetrahydrophthalimide were dissolved in 100 ml of N,N-dimethylformamide, and reacted and worked up in the same way as in Example 4. There was obtained 15.3 g (yield 85.9%) of benzil-di-(β-1,2,5,6-tetrahydrophthalimidoethyl)ketal.
