Versuchsvorschrift

A mixture of 3-fluoro-4-(morpholinomethyl)aniline (0.21 g, 1.00 mmol), anhydrous CH2Cl2 (10 mL) and trimethylaluminum (4.5 mL, 4.5 mmol, 1.0 M in heptane) was stirred at rt for 20 min under N2, followed by the addition of a solution of methyl 3-acetaminocrotonate (0.19 g, 1.20 mmol) in CH2Cl2 (5 mL). The reaction mixture was stirred at rt for 10 h, then quenched with saturated NH4Cl aqueous solution and extracted with CH2Cl2. The combined organic phases were washed with saturated NaHCO3 aqueous solution and brine, dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=1:1) to give the title compound as a pale yellow solid (0.105 g, 30%). The compound was characterized by the following spectroscopic data:
