Procedure

Following general procedure J and using [2-fluoro-4-(8,8-dimethyl-5-oxo-5,6,7,8-tetrahydro-naphthalene-2-ylethynyl)phenyl]acetic acid methyl ester (Compound 14, 0.18 g, 0.48 mmol), methanol (4 mL), tetrahydrofuran (8 mL), water (2 mL) and lithium hydroxide monohydrate (0.2 g, 4.76 mmol) followed by flash column chromatography over silica gel (230-400 mesh) using 50-100% ethyl acetate in hexane as the eluent, the title compound was obtained as a dirty white solid (0.068 g, 41%).
