Reaction Steps

To a solution of 42-(2-Iodo-3-trifluoromethyl-benzoylamino)-indan-2-carboxylic acid ethyl ester (A8) (500 mg, 1.10 mmol) and 2-methyl-1-propenyl boronic acid pinacol ester (400 mg, 2.20 mmol) in dioxane (20 mL) is added dichloro[1,1′-bis(diphenylphosphino)ferrocene]-palladium (II) DCM adduct (71.8 mg, 8.2% mmol) and 2M aqueous solution of K2CO3 (1.65 mL, 3.30 mmol). The resulting reaction mixture is filled in with N2, heated to 100° C. and stirred continuously overnight. Reaction mixture is filtered and concentrated in vacuo, and the resulting residue is purified by flash column chromatography (12 g silica gel, gradient elution: 0%-50% EtOAc in heptane) to give a pure product (396) as light brown oil (100 mg, 21%).
