실험 절차
3.30 g 4-Benzyl-2,2-dimethyl-piperazine-1-carboxylic acid tert-butyl ester were dissolved in 50 ml methanol, and 25 ml of 1N aqueous hydrochloric acid were added. After stirring overnight 5 ml of concentrated aqueous hydrochloric acid were added. After 2 h the volatiles were removed in vacuo and 2.40 g (97%) of the title compound were obtained as hydrochloride salt, which could be use without further purification.
