Product 1

HCID 123802781H-Indole-3-carbonyl chloride

Procedure

Indole 3-carboxylic acid, (2.0 g) was dissolved in 5 ml of SOCl2. The mixture was heated to reflux for 30 minutes. Removal of excess of SOCl2 under vacuum provided intermediate 9, indole 3-carbonyl chloride, which was carried to the next step without further purification.
