Procedure
Using 2-bromothiazole (5.0 g, 30.482 mmol) and (4-fluorophenyl)boronic acid (8.528 g, 60.964 mmol) as reactants and following the procedure described in Example 7 step 1, the title compound was obtained after purification by flash chromatography (60-120μ; 4% ethyl acetate in hexane) as colorless liquid (5.0 g, 91% yield). 1H NMR (400 MHz, DMSO-d6): δ 8.00-7.89 (m, 2H), 7.90 (d, 1H), 7.76 (d, 1H), 7.32 (t, 2H); LC-MS m/z calculated for [M+H]+ 180.02. found 180.1.
