実験手順

35 mL of 2N aqueous hydrochloric acid were added to a solution of 3.5 g (13.6 mmol) of 5-(tert-butyl-dimethyl-silanyloxy)-cyclooctylamine (59) in 35 mL 2-propanol and the resulting solution was stirred at room temperature overnight. The isopropanol was removed under reduced pressure and the resulting aqueous solution washed with t-butylmethylether. 2.7 g of crude 5-amino-cyclooctanol (60) was obtained by freeze-drying the aqueous layer as a diastereomeric mixture as hydrochloride which was used without further purification. Rt=0.18 min (Method C). Detected mass: 144.2 (M+H+).
