Reaction Steps

To a starting material (indole-7-carbaldehyde), a solution of 24 g of I2 in 125 ml of DMF (dimethylformamide) was added with stirring, and 5.3 g of KOH was added, after which the mixture was allowed to react. The termination of the reaction was confirmed with thin layer chromatography (TLC), after which layer separation was conducted with 354 ml of EA and 354 ml of purified water. The organic layer was washed with aqueous 10% Na2S2O3, dried with Na2SO4 (sodium sulfate), filtered and concentrated at 40, thus obtaining P10 as a concentrated residue.
