1-(4-benzylpiperazin-1-yl)prop-2-en-1-one

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 1-(1-Oxo-2-propenyl)-4-(phenylmethyl)piperazine (2.53 g, 0.011 mole) and 2,6-dichloro-4-mercaptophenol (2.15 g, 0.011 mole) were dissolved in methanol (75 ml). Triethylamine (1 ml) was added and the reaction stirred for 12 hours. The solvent was removed, and the product purified by chromatography on silica, eluting with ethyl acetate/hexane. The solvent was removed the product purified by chromatography on silica eluting with ethyl acetate/hexane

Procedure: Following the procedure of Example 4, 1-(1-oxo-2-propenyl-4-phenylmethyl)piperazine (Example 6) (2.30 g, 0.01 mole) was dissolved in methanol (150 ml) and triethylamine (1 ml) added to the solution. The solution was flushed with argon several times, 5'-mercapto [1,1':3',1"-terphenyl]-2'-ol (2.77 g, 0.01 mole) added and the reaction stirred for 12 hours. The solvent was removed and the product isolated by chromatography to yield 1.5 g of product after drying in vacuo. added The solvent was removed the product isolated by chromatography

Procedure: A solution of acryloyl chloride (4.52 g, 0.05 mole) in 25 ml of ethyl ether was added to a cold solution of 1-benzylpiperazine (8.8 g, 0.05 mole) and triethylamine (30 ml, 0.20 mole) in 500 ml of ethyl ether. A white precipitate formed. The reaction mixture was stirred overnight, filtered and the precipitate washed well with ethyl ether. The solvent and triethylamine were removed and the product chromatographed on silica, eluting with ethyl acetate/hexane [30:70 (v/v)] to yield 1.5 g of the title compound. The structure was confirmed by NMR.
