Versuchsvorschrift

A mixture of 0.65 g (0.25 mmol) of benzyl-1-methylindole-7-carboxylate (Step B) and 0.035 g of 10% Pd/C in 4 mL of a solution of 4.4% HCO2H in MeOH was stirred for 2 h at rt. The reaction mixture was filtered though a thin pad of celite and concentrated to give the title compound. 1H NMR (CDCl3) δ4.00 (s, 3H), 6.61 (d, 1H, J=3 Hz), 7.11 (d, 1H, J=3 Hz), 7.18 (t, 1H, J=8 Hz), 7.87 (d, 1H, J=8 Hz), 7.91 (d, 1H, J=8 Hz);
