Versuchsvorschrift

The product of Step b (0.15 g) was dissolved in THF (4 ml), bromo-tris-pyrrolidino-phosphonium hexafluorophosphate (PYBROP™; 0.235 g), 3-methylsulphonylbenzoic acid (0.091 g) and N,N-di-iso-propylethylamine (0.238 ml) were added. After 18 hours at room temperature ethyl acetate and aqueous NaHCO3 solution were added. The product was extracted with ethyl acetate, the combined organic extracts dried with Na2SO4 and concentrated. Purification by reverse phase HPLC (with a gradient eluent system (45% MeCN/NH4OAcaq (0.1%) to 95% MeCN//NH4OAcaq (0.1%)) gave the title compound (0.095 g).
