Reaction Steps

A 1.6M methyllithium solution in ethyl ether (3.4 ml, 5.4 mmol) is added to a solution of 3-Methyl-3-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)-2,3-dihydrobenzofuran-5-carboxylic acid (Example 2) (900 mg, 4.47 mmol) in THF (50 ml) at -20° C. The mixture is stirred for 4 h at -20° C. and is then poured onto ethyl acetate and a 1N hydrochloric acid solution. The organic phase is washed 2 times with water, dried over anhydrous magnesium sulphate and concentrated in vacuo at 40° C. in a rotary evaporator.
