Versuchsvorschrift

Charge a 3-gal autoclave with 7-nitroindole (250 g, 1.542 moles), 2B-3 ethyl alcohol (5.0 L), and 10% Pd/C (50.0 g). Stir at 50 psi H2 for 2 h at <27° C. When the reaction is deemed complete, filter the reactor contents through Celite followed by concentration of the filtrate to dryness to yield 197.0 g (96.7%) of the title compound as purple solid. 1H-NMR(CD3OD, 300 MHz), δ 7.16 (d, 1H), 7.00 (dd, 1H), 6.81 (t, 1H), 6.50 (dd, 1H), 6.37 (d, 1H).
