실험 절차
4-[5-(2,4-Dimethylbenzoyl)-1-methylpyrrol-2-ylmethyl)nitrobenzene (923 mg, 2.52 mmol) [prepared as described in Example 6, Step(e)], was dissolved in ethyl acetate (10 ml). 10% Pd/C (92 mg) was added, and the reaction mixture was vigorously stirred under hydrogen atmosphere at ambient temperature and atmospheric pressure for 2 h. The mixture was filtered through Celite®, and the filtrate was evaporated to dryness to give 4-[5-(2,4-dimethylbenzoyl)-1-methylpyrrol-2-yl-methyl)aniline (718 mg, 85%) as pale yellow crystals, mp 107.6-108.5° C.
