実験手順

The mixture (302.6 mg, 1.116 mmol) of N-(7-bromobenzo[d]thiazol-2-yl)acetamide and N-(6-bromobenzo[d]thiazol-2-yl)acetamide, 3-fluoro-4-methoxyphenylboronic acid (298 mg, 1.75 mmol), sodium carbonate monohydrate (0.247 mL, 4.48 mmol), and dichlorobis(triphenylphosphine)palladium (II) (168 mg, 0.239 mmol) were suspended in 1,2-dimethoxyethane (3.5 mL), water (1.5 mL) and EtOH (1.0 mL). The reaction flask was fit with a reflux condensor and placed in a preheated oil bath (85° C.) and stirred under argon for 1 hour. The reaction was cooled to room temperature and allowed to stand overnight. It was then filtered through a Celite® (diatomaceous earth) pad, and the solid was washed with MeOH, DCM, and DME. The filtrate was concentrated and treated with DCM. The resulting precipitate was collected by filtration and the crude was further purified by HPLC to provide N-(7-(3-Fluoro-4-methoxyphenyl)benzo[d]thiazol-2-yl)acetamide and N-(6-(3-Fluoro-4-methoxyphenyl)benzo[d]thiazol-2-yl)acetamide.
