Reaction Steps

The title compound was synthesized following the method herein described for the compound of Example 96, but replacing Compound 22c for Compound 27d and 2-furoyl chloride for methylisocyanate. After the usual work-up procedure the crude was purified by means of automated flash chromatography (Isolera®TM-Biotage; gradient Petroleum Ether-EtOAc from 95:5 to 8:2) giving 105 mg of the title compound. Yield: 60.2%.
