Morpholine → 4-(4-Bromobenzyl)morpholine

Participants

Reaction Steps

4-Bromobenzyl bromide (2.0 g) and morpholine (1.39 ml) were stirred in dimethylformamide (25 ml) for 18 h. The mixture was partitioned between diethyl ether (50 ml) and water (80 ml). The aqueous phase was extracted further with ether (50 ml) and the combined organics were washed with water (80 ml), dried (magnesium sulphate) and evaporated. The residue was purified by column chromatography, eluting with a gradient of ethyl acetate/iso-hexane; 0/100 to 50/50, to give the product as a white crystalline solid (1.44 g).
