SYNTHESIS To a solution of 1.21 g 5-methoxyindole-3-carboxaldehyde in 15 mL nitroethane there was added 0.3 g anhydrous ammonium acetate, and the mixture was held at steam-bath temperature. Periodic assay by TLC showed the reaction to be complete in 1.5 h. The volatiles were removed under vacuum, and the residue (1.58 g of rusty red crystals) was recrystallized from 15 mL boiling isopropanol. After filtration and air-drying, there was obtained 1.24 g (82%) of 5-methoxy-3-(2-nitropropenyl)indole as dull gold crystals with a melting point of 178-179 °C. The literature value is 182-184 °C. [Pg.262]
