Participants

Reaction Steps

A mixture of tert-butyl 3-(2-bromothiophen-3-yl)-3-hydroxypyrrolidine-1-carboxylate (5 g, 13.8 mmol), Pd(OAc)2 (31 mg, 0.14 mmol), Ph3P (147 mg, 0.42 mmol), 2-hydroxyphenylboronic acid (1.74 g, 27.6 mmol) and Na2CO3 (2.9 g, 27.6 mmol) in dioxane (10 mL) and water (10 mL) was refluxed under N2 for 3 h. After the reaction was cooled to room temperature, the reaction mixture was extracted with EtOAc several times. The combined organic layers were washed with brine, and dried over anhydrous Na2SO4. After filtration and concentration, the crude product was purified by column chromatography to give the title compound (4.4 g, 88%).
