Versuchsvorschrift

Tert-butyl 4-[8-(tert-butoxycarbonylsulfamoyl)-5,8-diazaspiro[2.5]octan-5-yl]pyrrolo[2,3-d]pyrimidine-7-carboxylate (intermediate 47) (0.55 mmol) was dissolved in dry THF (3 mL) and added [(2S)-1-benzylpyrrolidin-2-yl]methanol (0.61 mmol) and triphenylphosphine (0.66 mmol). The reaction mixture was cooled to 0° C. and slowly added isopropyl (NZ)—N-isopropoxycarbonyliminocarbamate (0.66 mmol). The reaction mixture was allowed to warm up freely to rt and stirred at rt for 16 h. The crude mixture was treated with water (50 mL) and extracted with EtOAc (3×50 mL). The combined organic phases were washed with H2O (2×50 mL), brine (2×50 mL), dried over Na2SO4, filtered and concentrated in vacuo. The product was purified by flash chromatography on silica using EtOAc in heptane as eluent.
