Dissolve 420 mg (0.81 mmol) (6R)-6-{[5-(4-ethylphenyl)-6-(2-fluorophenyl)furo[2,3-d]pyrimidin-4-yl]oxy}heptanoic acid tert.-butyl ester in 5.3 ml 4 N hydrogen chloride in dioxan and stir for 16 h at RT. After concentrating the reaction solution by evaporation under vacuum, purify the residue by preparative RP-HPLC (gradient: water/acetonitrile). 200 mg (53% of theor.) of the desired product is obtained.
