Reaktionsschritte
A solution of 0.29 g (2 mmol) of phenylpropynoic acid, 0.44 g (2 mmol) of [4-(2-diethylaminoethoxy)phenyl]methylamine, 0.7 g (2.2 mmol) of TBTU, 0.29 g (2.2 mmol) of HOBT and 0.51 mL (3 mmol) of Hünig base in 30 mL of THF and 2 mL of DMF is stirred for 14 hours at ambient temperature. The reaction mixture is evaporated down. The purification is carried out by column chromatography on silica gel (dichloromethane/methanol (80:20)). Yield: 130 mg (18.5% of theory); C22H26N2O2 (M=350.46); calc.: molecular ion peak (M+H)+: 351; found: molecular ion peak (M+H)+: 351; Rf value: 0.39 (silica gel, dichloromethane/methanol (80:20)).
