That is, in a nitrogen (N 2) atmosphere, 2,8-dimethoxynaphthalene (compound (201) ) (2.0 g, 11 mmol) was dissolved in dry tetrahydrofuran (hereinafter abbreviated as "THF") Dissolved in 20 mL of water was cooled to -10 C. To this solution was added tetramethylethylene Diamine (TMEDA) (3.2 mL) and n-butyllithium (2.4 M hexane solution) And 4.9 mL (12 mmol) was added dropwise. Under a nitrogen atmosphere, the obtained mixture was dissolved in 1h After stirring for a while, it was cooled to -78 C., 710 muL of <strong>[13671-00-6]methyl 2,6-difluorobenzoate</strong> (5.3 mmol) dissolved in 8 mL of dry THF was added over 10 minutes to the above Was added dropwise to the mixture, and the reaction was started.
