実験手順

To spermine tetrahydrochloride (4.53 g, 13.0 mmol) and 10% aqueous NaOH (200 mL, 132 mmol) at 0° is added dropwise p-toluene-sulfonyl chloride (9.98 g, 52.3 mmol) in CH2Cl2 with rapid stirring. After 1 hr the mixture is allowed to warm to room temperature and to stir for 2 days. The organic phase is separated and washed with 0.5N HCl, H2O, and brine, dried over Na2SO4 and purified on silica gel (450 g, 3% MeOH/CHCl3) to give 9.69 g, 91% yield of tetratosylspermine.
