Reaction Steps
A slurry of 1-(4-tert-butyl-2-nitrophenyl)-2,5-dimethylpyrrole (0.341 g, 1.25 mmol), 10% Pd/C (0.056 g) and EtOAc (50 mL) under an H2 atmosphere (balloon) was stirred for 72 h, then filtered through a pad of Celite®. The filtrate was concentrated under reduced pressure to give 5-tert-butyl-2-(2,5-dimethylpyrrolyl)aniline as yellowish solids (0.30 g, 99%): TLC (10% EtOAc/90% hexane) Rf 0.43; 1H NMR (CDCl3) δ 1.28 (s, 9H), 1.87-1.91 (m, 8H), 5.85 (br s, 2H), 6.73-6.96 (m, 3H), 7.28 (br s, 1H).
