実験手順

5-(1-Fluoro-2-piperazin-1-ylethyl)-4-methyl-2-benzofuran-1(3H)-one hydrochloride (30 mg, 0.11 mmol), 2-(methyloxy)-4-(2-oxoethyl)benzonitrile (37 mg, 0.22 mmol), sodium cyanoborohydride (67 mg, 1.078 mmol) were added to a 25 mL flask containing a stir bar; to the flask was added MeOH (3 mL) and few drops of AcOH. The reaction mixture was subsequently stirred for 12 hr; LC indicated that reaction had gone to completion. The solution was concentrated to dryness, redissolved in EtOAc (15 mL) and washed with aq. NaHCO3 and aq. NaCl. The organic phase was dried over Na2SO4, filtered and concentrated to dryness. It was then re-dissolved in MeOH (3.5 mL) again, filtered and shot into mass-directed HPLC for separation to give the desired product. LC-MS (IE, m/z): 450 [M+1]+.
