Methanol → 2-Methoxy-1-formylpiperidine

Participants

Reaction Steps

In the flow apparatus with cell as described in Example 1 a mixture of 4,800 g of 1-formylpiperidine, 13,600 g of methanol and 68 g of tetramethylammonium tetrafluoroborate was electrolyzed at 27.5 A, 42 volts and 25° C. for 27 hours and 33 minutes (corresponding to 2,273 Ahr). After distillative work up, 5,720 g of 1-formyl-2-methoxypiperidine were isolated, corresponding to a current efficiency of 86.9%.
