실험 절차

As described in General Procedure F-1, 1-(4-chloro-3-ethoxy-8-isopropyl-5,5-dimethyl-5,6-dihydronaphthalen-2-yl)-ethanone (Compound A-121, 0.23 g, 0.72 mmol) and triethyl 2-fluoro-2-phosphonoacetate (566 mg, 2.3 μmmol) were reacted with n-butyllithium (1.6 M in hexanes, 1.46 mL, 2.3 mmol) in THF to produce the title compound after purification by flash column chromatography (silica gel, 2% to 4% ethyl acetate in hexane).
