実験手順

3.58 g (15 mmol) of 1-(indan-4-yl)-piperazine hydrochloride and 3.62 g (15 mmol) of trans-4-(2-oxoethyl)cyclohexyl-carbamic acid tert-butyl ester were dissolved in dichloroethane (120 ml), 2.1 ml (15 mmol) triethylamine was added, then 4.6 g (22 mmol) sodium triacetoxyborohydride was added portionswise and the reaction mixture was stirred for 20 hours at ambient temperature, then 20% potassium carbonate solution in water (40 ml) was added. The organic layer was separated, dried and evaporated to dryness in vacuo. The precipitate was recrystallized from acetonitrile to give the title compound 5.5 g (yield: 85.8%), m.p.: 115-8° C.
