実験手順

A solution of zinc(II)chloride (0.5 M, THF, 0.5 eq., 234 uL) was added to a stirred solution of 1-(3-bromophenyl)-2-propanone (50 mg) and 2-methyl-5-(1-piperazinyl)quinoline (D3) (2.0 eq., 107 mg) in methanol (1 ml). The mixture was stirred 10 minutes then a solution of sodium cyanoborohydride (1M, THF, 1.0 eq., 234 uL) was. added. The resulting white mixture was stirred at room temperature until hplc showed the complete disappearance of starting material. The mixture was concentrated under reduced pressure, diluted with aqueous sodium hydroxide solution (1M), and extracted with DCM. The combined organic phases were washed with brine, dried over sodium sulfate and concentrated. The crude was purified by chromatography using a SPE cartridge (SiO2) with DCM-methanol (98:2) as eluent to afford the title compound (50 mg, 50% yield).
