A mixture of water/toluene/1,4-dioxane (1:1.8:5.5, 0.5 mL) was added and the resultingsuspension degassed with argon for 15 min. Subsequently, Pd2(dba)3 (0.4 mg, 0.437 μmol) and P(otol)3 (1.1 mg, 3.61 μmol) were added, and the reaction was heated to 60 °C for 14 h. Upon fullconversion of the starting material, the reaction was diluted with CH2Cl2 (10 mL) and washed withwater (15 mL) three times. The organic phase was dried over MgSO4, the solvent evaporated underreduced pressure and the crude purified by column chromatography (SiO2, gradient of hexane/CH2Cl2).

Then, n-butyllithium (100 mmol) was slowly added dropwise, and after stirring for one hour, 2-isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (100 mmol) was added. The reaction system was cooled to a room temperature, and stirred for another three hours. Water was added to the reaction system followed by separation, and the obtained crude product was purified by silica gel column chromatography (developing solvent: ethyl acetate) to obtain a compound A1 as a white fine crystal (42.7 mmol, yield: 43%).1H NMR (400 MHz, CDCl3) δ(ppm)=7.47 (d, 1H), 6.89 (d, 1H), 3.91 (s, 3H), 1.34 (s, 12H).
Stage #1: 3-methoxy-thiophene With n-butyllithium In tetrahydrofuran; hexane at -78℃; for 1h; Inert atmosphere; Stage #2: 2-Isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane In tetrahydrofuran; hexane at 20℃; 1 Synthesis example 1 In a three-necked flask, 3-methoxythiophene (5.7 g, 50 mmol) of the following formula (5), 250 ml of THF were added, and the atmosphere was purged with nitrogen, and cooled to -78° A 1.6 M normal butyl lithium hexane solution was added dropwise thereto, and after completion of the addition, the mixture was stirred at -78 ° C for 1 hour.To thereIsopropoxyboronic acid pinacol(16.2 ml, 80 mmol) was added, and the mixture was gradually returned to room temperature and stirred overnight. After water was added, it was extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, filtered and the solvent was evaporated. The obtained crude product was purified by silica gel chromatography (mobile phase: ethyl acetate / hexane) to obtain a thiophene derivative of the following formula (6) as a target product.
