Versuchsvorschrift

To a mixture of 2-benzyl-6-chloro-4-(4-formylphenyl)-1-oxo-1,2-dihydroisoquinoline-3-carboxylic acid methyl ester (93 mg), sodium dihydrogenphosphate (26 mg), 2-methyl-2-butene (100 μl), THF (2.0 ml), butanol (1.0 ml) and water (2.0 ml) was added sodium chlorite (73 mg) at 0° C. with stirring, and the mixture was stirred for 1 hr. The solvent was removed and the residue was partitioned between 1N hydrochloric acid and ethyl acetate. The organic layer was dried over magnesium sulfate and concentrated. The residue was purified by preparative HPLC to give the title compound (33 mg) as a colorless powder.
