Participants

Reaction Steps

A mixture of 1.03 g (3.33 mmol) of 1-(4-benzyl-piperidine-1-yl)-2-bromo-propan-1-one, 0.5 g (3.33 mmol) of 6-amino-3H-benzoxazol-2-one, 1.0 g (7.2 mmol) of potassium carbonate and 15 ml of dimethylformamide is refluxed for 5 hours. The reaction mixture is filtered and the filtrate is concentrated. The residue is purified by column chromatography using Kieselgel 60 adsorbent (Merck) and hexane:ethyl acetate=4:1 as eluent to yield 0.46 g (36.5%) of the title compound. Melting Point: 91° C.
