Reaction Steps

A solution of 50 mg (0.104 mmol) 1-[2-hydroxy-2-(2,4,6-trimethyl-phenyl)-ethyl]-4-(4-isopropyl-phenyl)-6-prop-2-ynyloxy-1H-quinazolin-2-one and 34.3 μl (0.208 mmol) trifluoromethane sulphonic anhydride in 0.5 ml 1,2 dichloroethane is heated to 80° C. for 15 min. Extraction with dichloromethane/aqueous NaHCO3 followed by preparative reversed phase HPLC yielded the title compound.
