Reaktionsschritte

A solution of 20.10 g (80.00 mmol) of (S)-2-(tert-butoxycarbonylamino-1-phenyl-propan-1-ol [J. Med. Chem. 33, 2707 (1990)] in 200 ml of a 4N solution of gaseous hydrogen chloride in anhydrous dioxane is stirred at room temperature for 30 min. After that, 60 ml of toluene are added and the mixture is concentrated in vacuo. This process is repeated a further two times and the residue is then triturated with a little ether, filtered off with suction and dried under high vacuum over KOH. 14.14 g (94% of theory) of the title compound are obtained as colourless crystals.
