Procedure

0.6 g of this dibromide were dissolved in 10 ml of THF, cooled to −78° C. and treated dropwise with 1.8 ml of a 1.6 molar solution of butyl lithium in hexane. After stirring at −78° C. for 1 hour and at room temperature for 1 hour, the reaction mixture was poured on ice/saturated aqueous ammonium chloride solution and extracted with hexane. The organic phase was dried (Na2SO4) and the solvent evaporated to yield 0.4 g of 2-ethynyl-4,4,7,7-tetramethyl-2-pentyl-2,3,4,5,6,7-hexahydro-1H-indene as yellowish oil.
