実験手順
4-Nitro-2-thiophenecarboxylic acid (1 g, 5.7 mmol) was added with stirring to a solution of SnCl2. 2H2O (3.25 g, 14.4 mmol) in concentrated HCl (10 ml). The mixture was stirred for 6 hours at ambient temperature and purified by subjecting to chromatography on HP20SS resin, using water as eluant, to give the title compound (0.59 g, 71%).
