[Uses]

5-(Aminomethyl)indole is used in the synthesis of Vigabatrin (V253000) bioisosteres as inhibitors of γ-aminobutyric acid aminotransferase (GABA-AT) inhibitors.
[Uses]

Reactant for preparation of:• ;HIV-1 integrase inhibitors targeting the catalytic domain and its ability for interaction with LEDGF/p751• ;Inhibitors of Gli1-mediated transcription in the Hedgehog pathway2• ;SCIO-469-like compounds for the inhibition of p38 MAP kinase3• ;4-(indol-5-ylamino)thieno[2,3-b]pyridine-5-carbonitriles as protein kinase c theta (PKC θ) inhibitors4• ;Non-covalent thrombin inhibitors5
[Synthesis]

5-Cyanoindole

C-(1H-INDOL-5-YL)-METHYLAMINE

81881-74-5

The hydrogenation reaction was carried out using Raney Nickel as a catalyst in a methanol solution containing ammonia with 5-cyanoindole as starting material. After completion of the reaction, the reaction solution was concentrated under reduced pressure to give a light yellow solid product, C-(1H-indol-5-yl)-methylamine (5.25 g, quantitative yield).
