Versuchsvorschrift
Benzil-di-(β-bromoethyl)ketal (13.26 g) and 8.91 g of sodium glutarimide were dissolved in 50 ml of N,N-dimethylformamide, and reacted at 50° C. for 7 hours. When the reaction mixture was poured into 200 ml of ice water, white crystals formed. These crystals were washed with water, and dried to give 13.6 g of benzil-di-(β-glutarimidoethyl)ketal.
