Sodium cyanoborohydride → 5-Fluoro-2-methoxy-4-(2-{4-[2-(1-oxo-1,3-dihydro-2-benzofuran-5-yl)ethyl]piperazin-1-yl}ethyl)benzonitrile

Participants

Reaction Steps

To a mixture of 5-[2-(piperazin-1-yl)ethyl]-2-benzofuran-1(3H)-one (94 mg, 0.33 mmol) and 5-fluoro-2-methoxy-4-(2-oxoethyl)benzonitrile (58 mg, 0.30 mmol) in methanol (3.0 mL) at 0° C. was added sodium cyanoborohydride (29 mg, 0.47 mmol) and the mixture was stirred at room temperature for 12 hours. The reaction mixture was concentrated and purified by mass-directed HPLC to provide 5-fluoro-2-methoxy-4-(2-{4-[2-(1-oxo-1,3-dihydro-2-benzofuran-5-yl)ethyl]piperazin-1-yl}ethyl)benzonitrile. LC-MS (IE, m/z): 424.3 [M+1]+. (0.068 μM)
