実験手順

Prepared using General Procedure 1. To 5-(2-bromothiazol-5-yl)-2-fluorobenzonitrile THZ INT-4 (0.100 g, 0.35 mmol), tert-butyldimethyl(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-inden-1-yloxy) silane IND INT-8 (0.143 g, 0.38 mmol) and sodium carbonate (0.112 g, 1.1 mmol) in dioxane (1.8 mL) and H2O (0.2 mL) was added tetrakis(triphenylphosphine)palladium (0.041 g, 0.035 mmol). The solution was degassed with N2 and the reaction mixture heated at 85° C. for 6 h. Upon cooling, the reaction mixture was diluted with brine and washed with DCM (3×100 mL). The combined organic layers were dried over MgSO4, filtered, and concentrated. The crude product was purified by chromatography (30% EA/Hexanes) to produce 0.05 g (32%) of 5-(2-(1-(tert-butyldimethylsilyloxy)-2,3-dihydro-1H-inden-4-yl)thiazol-5-yl)-2-fluorobenzo-nitrile as a white solid. LCMS-ESI (m/z) calculated for C25H27FN2OSSi: 450.6; found 451.1 [M+H] +, tR=4.84 min (Method 3).
