In the same manner as indicated in Example 6 there are electrolyzed 19.3 g of 1-formyl-2,2-dimethylazetidine and 54.7 g of methanol in the presence of 0.27 g of tetramethylammonium tetrafluoroborate as conducting salt. After throughput of 2.5 Faraday per mol of 1-formyl-2,2-dimethoxyazetidine the current is switched off. The calculated mean cell voltage is 32.6 volts. Work-up of the electrolysis solution gives 12.2 g of 1-formyl-4-methoxy-2,2-dimethylazetidine (boiling point 52° C./0.26 mbar; nD25 =1.4496), which corresponds to a product yield of 49.9% and a current efficiency of 39.9%.
