Reaction Steps

As shown in FIG. 27, in reaction (a) a mixture of prothionamide (9.01 g, 50.0 mmol) and 4-bromophenacyl bromide 6a (13.9 g, 50.0 mmol) in EtOH (400 mL) was stirred at 70° C. for 1 h. After cooled to room temperature, the precipitation was filtered off with EtOAc and washed with EtOAc and saturated aqueous NaHCO3. The organic layer was washed with brine, dried over Na2SO4, and concentrated to give 4-(4-bromophenyl)-2-(2-propylpyridin-4-yl)thiazole 2 (14.3 g, 79%) as a light-yellow solid.
