Versuchsvorschrift

Palladium tetrakis[triphenylphosphine](12.17 mg, 10.5 μM, 0.05 equiv) was added to a solution of Alloc-THP-PBD conjugate 15e (179 mg, 0.21 mmol), pyrrolidine (17.91 mg, 0.25 mmol, 1.2 eq) and triphenylphosphine (13.81 mg, 0.25 equiv) in DCM (5 mL). The reaction mixture was stirred at room temperature for 2 h at which point TLC showed completion of reaction. Excess DCM was removed by rotary evaporation under reduced pressure and the resulting residue dried in vacuo to remove pyrrolidone. The product was purified by high performance liquid chromatography (eluted with acetone:water gradient with 1% TFA) to give the product as a light yellowish solid, 16e (48 mg, 34% after HPLC purification).
