Cesium fluoride → Methyl 4-[4-(1,1-dimethylethyl)-1-cyclohexen-1-yl]benzoate

Participants

Reaction Steps

A mixture of Example 5A (286 mg, 1.0 mmol), (4-methoxycarbonylphenyl)-boronic acid (216 mg, 1.2 mmol), Pd(dppf)Cl2CH2Cl2 (37 mg, 0.05 mmol), and cesium fluoride (454 mg, 3.0 mmol) in dioxane (5 mL) was heated to 90° C., stirred for 16 hours, filtered through a pad of silica gel (10 g) with diethyl ether (5 mL) and concentrated. The concentrate was purified by flash column chromatography on silica gel with 5% ethyl acetate/hexanes to provide the desired product.
