Participants

Reaction Steps

Ethyl indene-2-carboxylic acid hydrazide, (17.4 g., 0.1 mol) in 200 ml. of carbon disulfide was treated with 22 g. (0.1 mol) of phosphorous pentasulfide, and the mixture stirred at reflux for 24 hours. The mixture was extracted with 3 portions of 10% sodium hydroxide solution and the organic phase was dried and concentrated to a solid. The thiohydrazide thus prepared was reacted with phosgene as described in EXAMPLE 4 to give the title product.
