Procedure

Following general procedure G and using 2-fluoro-4-(8,8-dimethyl-5-oxo-5,6,7,8-tetrahydro-naphthalene-2-ylethynyl)-benzoic acid ethyl ester (Compound 9, 0.132 g, 0.3 mmol), dichloromethane (4 mL), acetonitrile(2 mL), cyclopropyl amine(1 mL, 14.45 mmol), acetic acid (1 mL)and sodium cyanoborohydride (0.18 g, 2.86 mmol) followed by flash column chromatography over silica gel (230-400 mesh) using 16-20% ethyl acetate in hexane as the eluent, the title compound was obtained as a pale yellow oil (0.1 g, 82%).
