실험 절차

In 45 ml of ethyl acetate were dissolved 1.25 g (4.82 mmol) of 4-(acetylthio)-1-(tert-butoxycarbonyl)piperdine as described in Reference example 11, and 12.0 ml (48.2 mmol) of a 4N hydrogen chloride-ethyl acetate solution were added to the solution, followed by stirring of the resulting mixture at 50° C. for 4 hours. After cooling, the precipitated solid was collected by filtration and washed with hexane to obtain 885 mg (yield: 94%) of the desired compound as a slightly yellow powder.
