Reaction Steps

N-Benzyl ethanolamine (15.1 g, 100 mmol) was stirred in benzene (160 ml) at room temperature. Thionyl chloride (30 ml) was added dropwise over ten minutes. A white precipitate began to form immediately and the reaction mixture was warmed to 80° C. for 30 minutes. After cooling to room temperature the white solid was filtered off, washed with ether and dried. This solid was neutralised with sodium hydroxide solution and extracted with ethylacetate, washed with brine, dried (MgSO4) and evaporated to a yellow oil which was chromatographed on silica gel. Elution with petrol/ethylacetate: 1/1 afforded the title amine as a colourless oil, yield 6.75 g (40%).
