Versuchsvorschrift

6-Amino-1-naphtalenesulfonic acid (Dahl's acid) (1 eq, 0.5 mmol,) was dissolved in DMF containing N-methylmorpholine (NMM) (2 eq), and succinic anhydride (10 eq) was then added. After over night reaction the solvent was removed under reduced pressure and the product was purified by preparative RP-HPLC (Reversed Phase HPLC). The column (Phenomenex Luna C18 10μ, 22×250 mm) was eluted at 10 ml/min with a gradient of 5 to 15% acetonitrile (ACN) in 0.1% aq TFA over 40 min. The desired peak fractions collected from six consecutive runs were pooled and lyophilized affording 146 mg of pure N-(−5-Sulfo-naphthalen-2-yl)-succinamic acid 2. Analytical RP-HPLC: tR=16.7 min, (Phenomenex Luna 5μ, 4.6×250 mm, 5-15% ACN in 0.1% aq TFA over 20 min at 1 ml/min, λ=214 nm). Electrospray MS: [M+H]+ of product expected at 324.0 m/z, found at 324.0 m/z.
