Procedure
4-(4-Methylsulfamoyl-4,7-diaza-spiro[2.5]oct-7-yl)-pyrrolo[2,3-d]pyrimidine-7-carboxylic acid tert-butyl ester (intermediate 4) (0.047 mmol) was dissolved in dry DMF (0.5 mL) and added Cs2CO3 (0.071 mmol) and chloro-acetic acid methyl ester (0.071 mmol). Stirred at 40° C. for 2 h and then added H2O (1.5 mL). Extracted with EtOAc (3×1 mL) and the combined organic phases were washed with brine (1 mL) and concentrated in vacuo. The residual oil was treated with TFA (1 mL) at rt for 1 h. The crude reaction mixture was concentrated in vacuo and redissolved in DMSO (0.5 mL). The pure compound was obtained by standard preparative HPLC purification of the reaction mixture.
