実験手順

2.2 g (20 mmol) of triethylamine and a solution of 1.4 ml (10 mmol) of isobutyl chloroformate in 20 ml of dry methylene chloride are added dropwise, in succession, to a solution, cooled to -10°, of 2.37 g (10 mmol) of 4-benzyloxycarbonylaminobutyric acid in 50 ml of dry methylene chloride. The reaction mixture is stirred for one hour at -10° and then a strong current of hydrogen sulphide is passed through for 11/2 hours. After warming to room temperature, the mixture is cooled again and acidified with 2N sulphuric acid. The organic phase is separated, dried and concentrated in vacuo. The 4-benzyloxycarbonylaminothiobutyric acid obtained can be used without further purification.
