YieldReaction ConditionsOperation in experiment
82% With pyrrolidine; In ethanol; for 1.0h;Heating / reflux; To a solution of methyl 4-nitro-5-methylthiophene-2-carboxylate (1.50 g, 7.46 mmol) in ethanol (7.5 ml) were added 2,4-bisbenzyloxybenzaldehyde (2.49 g, 7.83 mmol) and pyrrolidine (0.65 ml, 7.83 mmol). After stirring for 1 hr with heating under reflux, the reaction mixture was allowed to cool to room temperature. The precipitated solid was collected by filtration. The solid was washed with ethanol (3 ml×3), and dried under reduced pressure to give methyl (E)-5-[2-(2,4-bisbenzyloxyphenyl)vinyl]-4-nitrothiophene-2-carboxylate (3.08 g, yield 82%). 1H-NMR (400 MHz, δppm, DMSO-d6) 8.08(1H, s), 8.04(1H, d, J=16.0 Hz), 7.64(1H, d, J=8.8 Hz), 7.60(1H, d, J=16.0 Hz), 7.50-7.32(10H, m), 6.87(1H, d, J=2.0 Hz), 6.73(1H, dd, J=8.8, 2.4 Hz), 5.26(2H, s), 5.17(2H, s), 3.86(3H, s).
