Participants

Reaction Steps

137.3 g (1.03 mol) of anhydrous aluminium chloride and 34.2 g (0.34 mol) of succinic anhydride are suspended in 500 ml of ethylene chloride and 54.5 g (0.311 mol) of 2-acetamido-indane are introduced at room temperature, with vigorous stirring. The mixture is stirred at room temperature for a further 2 hours, ice and 150 ml of concentrated hydrochloric acid are added, and the ethylene chloride is removed by steam distillation. On cooling, 4-(2-acetamido-indan-5-yl)-4-oxobutyric acid crystallises out from the aqueous solution. The acid is purified by being dissolved in 2N sodium hydroxide solution, the solution is filtered and the acid is reprecipitated by means of hydrochloric acid.
