Versuchsvorschrift

To a solution of the intermediate from step E (5.25 mmol) in DMF (60 mL) was added cyanuric chloride (3.12 g, 17 mmol) in three portions. After 30 minutes at room temperature, the reaction was quenched with water and extracted with ethyl acetate (2×). The organic layer was washed with water, brine and dried over anhydrous Na2SO4, filtered, and concentrated in vacuo. The residue was purified by flash chromatography (SiO2) using 30% ethyl acetate-hexanes to give the desired product (0.95 g) as a yellow solid.
