Procedimiento

At room temperature, 1.72 g (9.64 mmol) of N-bromosuccinimide are added a little at a time to a solution of 2.00 g (9.64 mmol) of 2-ethyl-4-(4-fluorophenyl)-1,3-thiazole in 40 ml of dichloromethane. After 2 h, 50 ml of water are added to the reaction mixture, and the organic phase is separated off, washed with saturated NHCO3 solution, dried over MgSO4 and concentrated under reduced pressure. This gives 2.47 g (85%) of the desired product; 1H-NMR(DMSO-d6) δ: 7.92 (m, 2H), 7.32 (m, 2H), 3.02 (q, 2H), 1.31 (t, 3H).
