Reaction Steps

5.0 g (12 mmol) of methyl 4-(2-p-methoxybenzenesulphonamido-indan-5-yl)-4-oxobutyrate and 3.0 g (60 mmol) of 99% hydrazine in 25 ml of glacial acetic acid are boiled for 30 minutes. The mixture is evaporated, water is added to the residue, and the reaction product is filtered off with suction and recrystallised from n-propanol.
