Methyl 2-nitrobenzoate → (2-Nitrophenyl)-(2-trimethylsilanylthiazol-5-yl)methanone

참여 물질

반응 단계

To a solution of 2-trimethylsilylthiazole (2.0 g, 12.7 mmol) in THF at −78 C was added BuLi (5.08 mL, 2.5 M, 12.7 mmol). The reaction was stirred at −78 C for 0.5 hr and methyl 2-nitrobenzoate (2.69 mL, 19.1 mmol) was added. The suspension was stirred at room temperature for 2 hr and quenched with ammonium chloride solution. The mixture was extracted with ethyl acetate and the combined organic layer was dried over sodium sulfate, concentrated and purified by column chromatography to give 2H (680 mg)
