実験手順

A mixture of 2-(2-benzothienyl)-3-methylbutanoic acid (0.5 g, 21.4 mmol) and KHCO3 (21.4 mmol) in 10 ml THF/DMF (1:1) is stirred for 10 minutes. Then the mesylate of α-cyano-3-phenoxybenzyl alcohol (0.65 g, 21.4 mmol) in 3 ml THF is added followed by stirring overnight. The mixture is diluted with 100 ml ether, washed with water and saturated NaCl, dried and solvent stripped to yield crude product. The product is isolated using thin layer chromatography developing with 15% ethyl acetate/hexane to give α-cyano-3-phenoxybenzyl 2-(2-benzothienyl)-3-methyl-butanoate, viscous liquid.
