Reaktionsschritte
A mixture of 4-N,N-dimethylaminobenzaldehyde (3 g, 20 mmoles), N-(5-carboxy-pentyl)picolinium bromide (5.6 g, 20 mmoles) and piperidine (2 mL) in ethanol (100 mL) was heated at 60° C. overnight. The mixture was evaporated to dryness in vacuo. The residue was redissolved in methanol and then precipitated with ether to give the product (6.7 g).
