Versuchsvorschrift

14.9 g (0.1 mol) of 4-(N,N-dimethylamino)benzaldehyde were reacted with 23.6 g (0.1 mol) of 4-methyl-N-methylpyridinium iodide, prepared according to Example 3, and the resulting solution was treated with 34.6 g (0.1 mol) of sodium tetraphenyborate, under the conditions described in Example 6, to form dye2 as a red solid in a yield of 70%. 1H-NMR (DMSO-d6) δ 3.00 (s, 6H), 4.1 (s, 3H), 6.70 (t, 4H), 6.8 (t, d, 2H), 6.9 (t, 8H), 7.02 (d, 1H), 7.10 (d, 8H) 7.50 d, 2H), 7.9 (d, 2H), 8.62 (d, 2H) ppm. Td 266° C.
