Application
TCI Practical Example: Formylation of Aromatic Compound Using Vilsmeier Reagent
-
Used Chemicals
-
Procedure
-
To a solution of Vilsmeier reagent (1.09 g, 8.54 mmol, 2.0 eq.) in DMF (8.5 mL) was added indole (500 mg, 4.27 mmol) at 0 °C and the solution was stirred for 2.5 h at room temperature. The reaction mixture was quenched with 1 mol/L NaOH aq. (13 mL) and diluted with water (12 mL). The solution was poured into ice-cooled water (25 mL) and stirred for 1 h at the same temperature. The precipitation was collected by filtration, washed with water (3 x 3 mL), and dried under reduced pressure to give indole-3-carbaldehyde as a pale yellow solid (529 mg, 77% yield).
-
Experimenter’s Comments
-
The reaction mixture was monitored by TLC (ethyl acetate:hexane = 1:1, Rf = 0.32).
Since Vilsmeier reagent has hydroscopicity, it was quickly weighed and used.
