The title compound was prepared following the procedure described for Compound 3c, using Compound 91d instead of Compound 3b and Compound 89a instead of Compound 3a. After the usual work-up procedure, the residue was purified by means of automated flash chromatography (ISOLERA®TM-Biotage; gradient Petroleum Ether-EtOAc from 97:3 to 9:1) to give the title compound as a white-yellowish solid. Yield: 55.8%.
