Reaction Steps

To a solution of methyl 2-bromothiazole-5-carboxylate 1 (222 mg, 1.00 mmol) in acetonitrile (20 mL) were added N-phenyl ethyl piperazine 14e (228 mg, 1.20 mmol) and potassium carbonate (152 mg, 1.10 mmol) under a N2 atmosphere. The reaction mixture was heated to reflux at 80° C. for 10 h. The reaction mixture was filtered through Celite and the filtrate was concentrated under reduced pressure. The residue was purified by column chromatography using silica gel to give the compound 15e (245 mg, 66.4%).
