Procedure
Using 5-bromothiazole (1.0 g, 6.09 mmol) and (4-fluorophenyl)boronic acid (1.0 g, 7.31 mmol) and following the procedure described in example 7 step 1, the title compound was obtained after purification by purified by Biotage IsoleraOne® column (10% ethyl acetate in hexane) as yellow viscous liquid (0.4 g, 36% yield). 1H NMR (400 MHz, DMSO-d6): δ 9.05 (s, 1H), 8.25 (s, 1H), 7.73-7.69 (m, 2H), 7.27 (t, 2H); LC-MS m/z calculated for [M+H]+ 180.02. found 180.1.
