COMPOUND 36; 5.10,15-tris-[4-(3-Trimethyl-ammoniopropyloxy)-phenyl]-20-(4- tetradecyloxy-phenyl )-porplryrin trichloride; The n-tetradecyloxy-analogue of Compound 2, prepared similarly as described above for Compound 2 but using 1-bromotetradecane in place of 1-bromoundecane, (50 mg, 0.057 mmol) and (l-bromopropyl)- trimethylammonium bromide (210 mg, 0.8 mmol) are dissolved and K2CO3 (230 mg, 1.7 mmol) is suspended in DMF (20 mL). The vigorously stirred mixture is stirred at this temperature for 18 h. After removal of DMF under reduced pressure the residue obtained is dissolved in methanol (5 mL) and filtered through a pad of silica gel (depth 2 cm) supported on a steel frit (diameter 3.5 cm). After washing the pad with methanol (ca. 500 mL) it is eluted with acetic acid:methanol .-water (3 :2:1, by vol.). After evaporation of the solvent from appropriately combined fractions, the residue obtained is purified by chromatography on a column (2.5 x 40 cm) of Sephadex LH-20 eluting with n-butanol:water:acetic acid (4:5:1, by vol., upper phase) for separation from the excess of ammonium salt and other contaminating materials. After elution and removal of the solvent from appropriate fractions, the residue obtained is dissolved in methanol (5 mL) and passed through a short column (3.5 x 20 cm) of anion exchange resin (Amberlite IRA 400, chloride form). Solvent is removed under reduced pressure and the residue obtained is dried under high vacuum to afford the product as a violet solid.1H-NMR: deltaH (300MHz, CD3OD): 0.75 (t, 3J 7.5 Hz, 3 H), 0.95-1.25 (m, 22 H), 1.50-1.65 (bs, 2 H), 2.20-2.40 (bs, 6 H)5 3.05-3.15 (bs, 27 H), 3.45-3.60 (bs, 6 H), 3.60-3.80 (bs, 2 H), 4.05-4.25 (bs, 6 H), 6.80-7.25, 7.65-8.05, (2 x m, 16 H)5 8.45-8.95 (bs, 8 H)., 3779-42-8
3779-42-8 3-Bromo-N,N,N-trimethylpropan-1-aminium bromide 151145, acatalyst-ligand compound, is more and more widely used in various fields.
