실험 절차

6.0 g (21.1 mmol) of methyl 4-(2-amino-indan-5-yl)-4-oxobutyrate hydrochloride are suspended in 60 ml of chloroform and 5.0 g (25.3 mmol) of p-toluenesulphonyl chloride are added. 5.1 g (50 mmol) of triethylamine are added, with vigorous stirring, a clear solution being formed. After 20 hours at room temperature, the mixture is washed with water, the chloroform solution is evaporated and the residue is recrystallised from methanol.
