Reaktionsschritte

A solution of methyl (E)-3-(4-nitrophenyl)acrylate (S31, 4.10 g, 19.8 mmol) in MeOH (30 mL) and THF (30 mL) was treated with 10% Pd/C (400 mg). The reaction mixture was purged with H2 and was stirred at 25° C. for 10 h. The suspension was filtered through diatomaceous earth and concentrated to afford S32 (3.40 g, 19.0 mmol, 95%) as a yellow solid: 1H NMR (CDCl3, 500 MHz) 6.99 (d, 2H, J=8.2 Hz), 6.63 (d, 2H, J=8.4 Hz), 3.60 (s, 3H), 2.85 (t, 2H, J=7.7 Hz), 2.58 (t, 2H, J=7.7 Hz); 13C NMR (CDCl3, 125 MHz) 173.5, 144.6, 130.5, 129.1, 115.3, 51.5, 36.1, 30.1.
