Procedure

To a solution of Intermediate 13 (100 mg, 0.24 mmol) and 10 mL of anhydrous benzene under argon at 25° C. was added 4-acetylphenyl isocyanate (43 mg, 0.26 mmol) and triethylamine (50 mg, 0.48 mmol). The resulting mixture was heated to 100° C. for 12 hours and the reaction was quenched with water. The product was extracted with EtOAc, the layers were separated, and the organic layer was washed with brine, and dried over Na2SO4, and filtered, and concentrated under reduced pressure. The residue was purified by medium pressure liquid chromatography on silica gel using ethyl acetate:hexane (85:15) to yield Intermediate 23 as a light yellow solid.
