Versuchsvorschrift
A solution of 2-[4-(3-chloropropoxy)phenyl]-1,3-thiazole i88 (120 mg, 1 eq, 0.47 mmol) in acetonitrile (1 ml) is added to a solution of sodium iodide (10 mg, 0.1 eq, 0.07 mmol) and 2-methylpyrrolidine (0.1 ml, 2 eq, 0.9 mmol) in acetonitrile (1 ml). The mixture is stirred at 85° C. overnight, filtered, washed with acetonitrile, and concentrated under reduced pressure. Purification of the residue by chromatography over silicagel (eluent: dichloromethane/methanol/ammonia 96/4/0.4) affords 40 mg of 2-{4-[3-(2-methylpyrrolidin-1-yl)propoxy]phenyl}-1,3-thiazole 83.
