Reaction Steps

To a suspension of pyrrole-2-carbaldehyde (277.8 mg, 2.92 mmol), 1,1-dimethylnitroethane (601.1 mg, 5.83 mmol) and zinc (572.5 mg, 8.76 mmol) in ethanol (4.0 ml) was added acetic acid (1.05 g, 17.5 mmol) dropwise at 5° C. while stirring. The mixture was stirred at room temperature for one day. Zinc acetate in the mixture was filtered off and the filtrate was concentrated and purified by silica gel chromatography (hexane/ethyl acetate=1/1-2/3).
