実験手順
To a mixture of 3-Methyl-1-[2-(4-nitrophenyl)ethyl]piperazin-2-one hydrochloride (38 mg, 0.13 mmol) and (4-Nitrophenyl)acetaldehyde (31 mg, 0.19 mmol) was added_titanium(IV) isopropoxide (0.37 mL, 1.3 mmol). After stirring the mixture at RT for 15 minutes, ethanol (2 mL) and sodium cyanoborohydride (80 mg, 1.3 mmol) were added to the reaction. The mixture was allowed to stir at RT for 16 hours. The reaction was diluted with ethyl acetate, washed with brine, dried over sodium sulfate, and concentrated to give the crude title product. The title product was purified by mass-directed reverse phase HPLC (AcCN-Water with 0.1% TFA). LC-MS (IE, m/z): 413 [M+1]+.
