Reaction Steps

Under nitrogen, 27.1 g (0.71 mol) of lithium aluminium hydride are introduced into 300 ml of absolute tetrahydrofuran, and a solution of 57 g (0.21 mol) of 4-(tert.-butyloxycarbonylamino)-1,3-dioxo-1,3,3a,4,7,7a-hexahydroisoindole in 570 ml of absolute tetrahydrofuran is added dropwise. The mixture is then refluxed overnight. 27.1 g of water in 82 ml of tetrahydrofuran, 27.1 g of 10% strength sodium hydroxide solution and 81.3 g of water are then added dropwise to the cold batch. The salts are filtered off with suction and washed with tetrahydrofuran, and the filtrate is concentrated in vacuo. The residue is distilled off under a high vacuum.
