The reaction solution was stirred at 40° C. overnight. The reaction solution was diluted with 1 N HCl solution and ethyl acetate and the aqueous layer was extracted with ethyl acetate once. The aqueous layer was neutralized with 50% NaOH solution to pH 10, and then extracted with EtOAc twice. The combined organic solutions were dried over sodium sulfate, filtered and concentrated. The residue was purified by flash column chromatography to yield the desired product (410 mg, 50%). LCMS calculated for C28H34ClN6O2(M+H)+: m/z=521.2.
