Participants

Reaction Steps

A mixture of the product of Step C (0.1 g; 0.27 mmol) and 10% Pd/C (0.1 g) in EtOH (15 ml) was stirred at room temperature for 1 h under H2 (balloon). The catalyst was removed by filtration through the Celite pad, washed with CH2Cl2 (2×10 ml) and combined filtrates were evaporated to dryness under reduced pressure to give a title compound (0.09 g; 90%), as colourless solid. 1H-NMR (CDCl3) 7.71 (d, 1H, J=8.8 Hz); 6.94 (d, 1H, J=8.8 Hz); 6.93 (s, 1H); 5.29 (m, 1H); 4.14 (q, 2H, J=7 Hz); 3.82 (t, 2H, J=8.8 Hz); 3.57 (q, 2H, J=5.9 Hz); 3.11 (t, 2H, J=8.6 Hz); 2.59 (t, 2H, J=5.7 Hz); 2.51 (t, 2H, J=7.7 Hz); 1.57 (m, 2H); 1.26 (m, 13H); 0.86 (t, 3H, J=7 Hz).
