Procedure

Triphenylmethanethiol (11.90 g, 43.08 mmol) was suspended in DMSO (40 mL). DBU (7.41 mL, 49.55 mmol) and 6-bromohexylphthalimide (13.32 g, 42.94 mmol) were added, and the mixture was allowed to react for approximately 15 min. The reaction mixture was partitioned between ethyl acetate (700 mL) and 0.1 M HCl (200 mL). The aqueous phase was extracted with ethyl acetate (3×50 mL), and the combined organic fractions were washed with NaHCO3 sat. (80 mL) and brine (80 mL), dried over MgSO4, filtered and concentrated. The crude yellow oil was recrystallized from n-heptane/ethyl acetate. The intermediate 6-(S-Trityl-)mercaptohexylphthalimide was obtained as a white solid (13.3 g, 26.4 mmol, 62%).
