実験手順

8.2 mg (0.18 mmol) of sodium hydride (55% suspension in mineral oil) were added to 17.8 mg (0.19 mmol) of 2-hydroxypyridine in 5 ml of DMF, and the mixture was stirred at room temperature for 30 min. Subsequently, 50 mg (0.17 mmol) of 5-(3-bromopropyl)-2-(2-fluorophenyl)pyridine were added. The reaction mixture was stirred for 4 h, concentrated, admixed with water and extracted with methylene chloride. The organic phase was separated and concentrated, and the residue was purified by preparative HPLC (RP18, acetonitrile/water containing 0.1% TFA) Yield: 11 mg (22%).
