Procedure

Cesium carbonate (2.17 g, 6.68 mmol) was added to a solution of 2-(2-amino-pyrimidin-4-yl)-3-iodo-4-oxo-1,4,6,7-tetrahydro-pyrrolo[3,2-c]pyridine-5-carboxylic acid tert-butyl ester (1.38 g, 3.03 mmol) in DMF (60 mL) and the mixture was stirred at room temperature for 1 h. Methyl iodide (0.948 g, 6.68 mmol) was then added and after 2 h stirring at room temperature, water (0.100 mL) and DCM (0.100 mL) were poured into the reaction vessel. The organic layer was separated, dried over Na2SO4, and concentrated under vacuum to yield the crude 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 as a brown solid (0.854 g, 1.8 mmol, 60%).
