Reaktionsschritte

Chloroacetyl chloride (0.16 ml, 2.0 mmol, 1 equiv.) was added to a stirred solution of 7-Octyn-1-ol (300 mg, 2.4 mmol, 1.2 equiv.) in CH2Cl2 (6 m-) at −5° C. The reaction mixture was allowed to warm-up to r.t., were it was stirred for 4 h. The solvent was removed under reduced pressure and the residue was purified by column chromatography on silica eluting with EtOAc/hexane (10%) to give the desired compound as a pale yellow liquid (450 mg, 100%).
