Procedure

Bromoacetylbromide (54 μl, 0.62 mmol) was dissolved in 0.5 ml CH2Cl2 and added to a solution of H2N—CH2—CH2-STrt (200 mg, 0.56 mmol) and DIEA (196 μl, 1.1 mmol) in CH2Cl2 (1 ml). The mixture was stirred for 1 h at RT. The reaction mixture was acidified with AcOH (100 μl) and the solvent was removed in vacuo. The residue was purified over silica gel (heptane/EtOAc=1:1) to obtain product Br—CH2—CONH—(CH2)2-STrt.
