Participants

Reaction Steps

A solution of 80.0 mg (0.173 mmol) of ethyl 4-[(5,6-dihydro-5,5-dimethyl-8-(4-(1,1-dimethylethyl)phenyl)-2-naphthalenyl)ethynyl]benzoate (Compound 6) and 18.1 mg (0.432 mmol) of LiOH-H2O in 6 ml of THF/water (3:1, v/v), was stirred overnight at room temperature. The reaction mixture was extracted with hexanes, and the remaining aqueous layer acidified with 1M HCl, and then extracted with EtOAc. The combined organic layers were dried over Na2SO4 and concentrated in vacuo to give the title compound as a colorless solid. 1H NMR (d6-DMSO): δ 7.82 (2H, d, J=8.2 Hz), 7.44 (6H, m), 7.25 (2H, d, J=8.3 Hz), 7.02 (1H, s), 6.01 (1H, t, J=4.6 Hz), 2.32 (2H, d, J=4.7 Hz), 1.32 (9H, s), 1.29 (6H, s).
