참여 물질

반응 단계

The mixed solution of 3-bromo-4-methoxybenzaldehyde (200 mg, 0.93 mmol) in methanol (4 mL) was added tosylmethyl isocyanide (200 mg, 1.02 mmol) and K2CO3 (260 mg, 1.88 mmol). The reaction was stirred at room temperature for 5 min before heated to 80° C. in the sealed tube. After 30 min, the solution was cooled to room temperature and concentrated. Column chromatography afforded 5-(3-bromo-4-methoxyphenyl)oxazole (o) (190 mg, 80%). Following the procedures analogous to the Suzuki and amide coupling reactions described for Compound 20, Compound 25 was prepared.
