Versuchsvorschrift

To a solution of 1-[3-(4-fluoro-phenoxy)-propyl]-1,3-dihydro-benzoimidazol-2-ylideneamine (0.96 g, 3.36 mmol) in 2-butanone (50 ml) was added 4-bromomethyl benzaldehyde (1.0 g, 5.03 mmol). The reaction was heated to reflux where it was maintained for 48 h. After this time, the suspension was cooled to rt and filtered. The collected solid was washed with additional 2-butanone and then dried to provide 4-{3-[3-(4-fluoro-phenoxy)-propyl]-2-imino-2,3-dihydro-benzoimidazol-1-ylmethyl}-benzaldehyde hydrobromide salt (0.80 g, 49%) as a yellow solid which was used without further purification. HPLC-MS 404 [M+1]+.
