실험 절차

Sodium hydride (95 mg of a 60% suspension in mineral oil; 2.4 mmol) was suspended in 22 mL of DMF in a flame-dried, argon-filled flask and stirred for about 5 min. 1-(2-Hydroxyethyl)pyrrolidine (0.23 mL; 2.0 mmol) was added and the mixture was stirred for 15 min. 3-Bromo-4-fluorophenyl 6-methoxy-2-[4-[2-(1-pyrrolidinyl)ethoxy]phenyl]benzo[b]thiophen-3-yl ketone in 3 mL of DMF was then added. The mixture was stirred for 4 h at room temperature, then poured into water (25 mL), and extracted with EtOAc (4×25 mL). The combined organics were washed with brine and dried over magnesium sulfate. The title compound (135 mg; 10% yield) was isolated by flash chromatography on silica gel eluting with a gradient of EtOAc(100-90%)/Et3N(0-5%)/MeOH(0-5%).
