Reaction Steps
650 mg (1.2 mmol) of methyl 4-[4-(3-fluorobenzyloxy)-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthylselanylethynyl]benzoate are dissolved in 20 mL of THF. 10 mL of water are added, followed by addition of 240 mg (6 mmol) of sodium hydroxide. The medium is stirred for 4 hours at 80° C. and then acidified with 1 N hydrochloric acid and extracted with ethyl acetate. The residue obtained is purified by chromatography (eluent: 1/1 heptane/ethyl acetate) and then recrystallized in a heptane/ethyl acetate mixture. A pure yellow crystalline solid is obtained (m=577 mg; yield=90%; m.p.=206° C.
