Versuchsvorschrift

A mixture of 3.0 g of 9,10-dimethoxy-3,4,6,7-tetrahydro-2H-pyrimido(6,1-a)isoquinolin-2,4-dione and 15.0 g of triethyloxonium fluoroborate in 100 ml of dichloromethane is stirred overnight. The reaction mixture is washed with a solution of sodium carbonate. The organic layer is separated and dried over anhydrous sodium sulfate. Evaporation of the solvent gives the title compound, yield 1.8 g.
