Reaktionsschritte

An ice-cooled solution of 2.63 ml (35 mmol) of allylamine in 14.2 ml of absolute pyridine and 14.2 ml of absolute THF is admixed dropwise with 5-chloro-thiophene-2-carbonyl chloride (7.61 g, 42 mmol). Ice-cooling is removed and the mixture is stirred at room temperature for 3 h and then concentrated under reduced pressure. The residue is admixed with water and the solid is filtered off. The crude product is purified by flash chromatography over silica gel (dichloromethane).
