Reaction Steps

A mixture of 2-(2-benzothienyl)-3-methylbutanoic acid (1 g, 4.3 mmol), 3-phenoxybenzyl bromide (1.1 g, 4.3 mmol) and K2CO3 (8.6 mmol) in 25 ml of THF/HMPA (1:1) is stirred overnight. The reaction is worked up by diluting with ether, washing with water, drying over Na2SO4, and solvent removed to yield 3-phenoxybenzyl 2-(2benzothienyl)-3-methylbutanoate which can be further purified by preparing thin layer chromatography eluting with 5 percent ether/hexane.
