Versuchsvorschrift

Pthaloyl chloride (0.089 g, 0.437 mmol) was added to a cold (0° C.) solution of 2-(2-Amino-pyrimidin-4-yl)-3-iodo-1-methyl-4-oxo-1,4,6,7-tetrahydro-pyrrolo-[3,2-c]-pyridine-5-carboxylic acid tert-butyl ester (prepared as described in Example 1) (0.158 g, 0.337 mmol) and pyridine (0.069 g, 0.875 mmol) in dry DCM (1.5 ml) and the reaction mixture was stirred at room temperature in argon atmosphere for 4 h. The organic layer was washed with a saturated solution of NaHCO3 (1×2.0 ml), brine (1×2.0 ml), and it was dried over Na2SO4. The filtrate was evaporated to dryness to give the crude product, which was purified by flash chromatography, over silica gel (DCM/MeOH (9.8:0.2) as eluent), to afford 2-[2-(1,3-dioxo-1,3-dihydro-isoindol-2-yl)-pyrimidin-4-yl]-3-iodo-1-methyl-4-oxo-1,4,6,7-tetra-hydro-pyrrolo[3,2-c]pyridine-5-carboxylic acid tert-butyl ester (0.150 mg, 0.25 mmol, 74%).
