Procedure

69 mg of {4-[5-(2,5-difluoro-phenoxy)-7-propoxy-oxazolo[5,4-d]pyrimidin-2-yl]-2,6-dimethyl-phenoxy}-acetic acid tert-butyl ester were dissolved in 1.6 ml of dichloromethane and treated with 0.8 ml of trifluoroacetic acid. After 16 h the mixture was concentrated and freeze-dried. 71 mg of the title compound were obtained.
