Procedure

60.2 mg (1.38 mmol) of sodium hydride (55% suspension in mineral oil) were added to 161.7 mg (1.38 mmol) of thiomorpholin-3-one in 5 ml of DMF, and the mixture was stirred at room temperature for 15 min. Subsequently, 350 mg (1.25 mmol) of 2-bromo-5-(3-bromopropyl)pyridine were added. The reaction mixture was stirred for 3.5 h, concentrated, admixed with water and extracted with ethyl acetate. The organic phase was separated and concentrated. Yield: 421 mg.
