Intermediate 1J (0.20 g, 0.42 mmol) was dissolved in dioxane (4 mL) and phenylboronic acid (0.10 g, 0.85 mmol) was added, followed by 2N Na2CO3 solution (0.70 mL, 1.39 mmol). The resulting mixture was degassed with nitrogen and tetrakis(triphenylphosphine) palladium(0) (0.073 g, 0.06 mmol) was added. The mixture was heated in a microwave reactor at 150° C. for 20 min. The reaction mixture was filtered through a celite pad, rinsed with methanol and the combined filtrate and washings were concentrated. The residue was purified by normal phase chromatography, eluting with 0-100% hexanes/ethyl acetate to provide Compound 1 as a yellow solid (0.15 g, 75%).
