COMPOUHD 48; 5-(4-Nonyloxy-phenyl)-10J5,20-tris-[4-(3-trimethylammonio- propyloxy)-phenyl] -porphyrin trichloride; Compound 45 (50 mg, 0.062 mmol) and (3-bromopropyl)- trimethylammonium bromide (162mg, 0.62 mmol, lOeqv.) are dissolved and potassium carbonate (128 mg, 0.93 mmol, 15 eqv.) is suspended under argon in absolute DMF (30 mL) and the mixture is stirred at 550C for 12 h. The solvent is removed in vacuo at 5O0C and the residue re- dissolved in a little methanol and applied to a pad of silica (2 cm deep). The unreacted ammonium salts are washed off with methanol (lOOOmL). The product is eluted with acetic acid:methanol:water (3 :2:1 by vol.). The solvents are removed under reduced pressure and the product further purified by chromatography on a column (10Og) of Sephadex LH-20 eluting with n-butanol:water:acetic acid (4:5: 1 by vol., upper phase). The solvents are removed under reduced pressure, the residue re-dissolved in a little methanol and the solution is passed through a short column of anion exchange resin (Amberlite IRC 400, chloride form) using methanol as eluent. After removal of solvent, the product is dried at high vacuum o give a violet solid. 1H-NNZ[R: deltaH (300MHz, CD3OD): 0.89 (t, 3H, 3J= 7.5 Hz). 1.18-1.34 (m, 10H)5 1.41 (bs, 2H), 1.73 (quint 2H, 3J- 7.5 Hz), 2.30-2.44 (m, 6H), 3,31 (bs, 27H)5 3.65-3.73 (m, 6H)5 3.93 (t 2H, 3J = 7.5 Hz)5 4.25-4.42 (m, 6H), 7.08 (d, 2H5 3J= 7.5 Hz)5 7.30 (d, 6H, 3J= 7.5 Hz)5 7.93 (d, 2H5 3J= 7.5 Hz)5 8.05 (d, 6H5 3J= 7.5 Hz), 8.94 (bs, 8H)
3779-42-8, The synthetic route of 3779-42-8 has been constantly updated, and we look forward to future research findings.
