HCID 211827494-[4-(1-Pyrrolidinyl)butoxy]phenyl 2-[4-[2-(1-Pyrrolidinyl)ethoxy]phenyl]benzo[b]thiophen-3-yl Ketone Dioxalate Hydrate収率 66%

実験手順

Sodium hydride (49 mg of 60% NaH in mineral oil; 1.23 mmol) was suspended in 3 mL of dry DMF in a flame-dried, argon-filled flask. After stirring for 15 min, a solution of 4-(1-pyrrolidinyl)butanol (Part B) in 1 mL of dry DMF was added. After stirring for 15 min and gas evolution had ceased, 4-fluorophenyl 2-[4-[2-(1-pyrrolidinyl)ethoxyl]phenyl]benzo[b]thiophen-3-yl ketone (Part A) (0.2 g; 0.49 mmol) in 1 mL of dry DMF was added. The mixture was stirred at room temperature for 5 h, then poured into 25 mL of water. Extraction was carried out with Etoac (4×25 mL). The combined organics were washed with brine and dried by passage through sodium sulfate. The title compound (0.18 g; 66% yield) was isolated as a colorless oil by flash chromatography on silica gel, eluting with a gradient of EtOAc(100-85%)/Et3N(0-5%)/MeOH(0-10%). Conversion to the dioxalate was effected as in Example 137, Part E.
