Versuchsvorschrift

To a solution of N-((5-tosyl-5H-pyrrolo[2,3-b]pyrazin-2-yl)methyl)cyclohexanecarboxamide (0.081 g, 0.196 mmol) in THF (1 mL) at ambient temperature was added 2,4-bis(4-phenoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide (0.104 g, 0.196 mmol, TCI). After about 15 h, the reaction mixture was concentrated under reduced pressure. The residue was suspended in EtOAc/DCM (1:1) and filtered through a plug of silica gel (5 g) eluting with EtOAc/DCM (1:1, approximately 100 mL). Concentration of the filtrate provided the crude N-((5-tosyl-5H-pyrrolo[2,3-b]pyrazin-2-yl)methyl)cyclohexanecarbothioamide. The crude thioamide was dissolved in THF (1 mL) and diacetoxymercury (0.0626 g, 0.196 mmol) was added. After about 30 min at ambient temperature, additional diacetoxymercury (0.0626 g, 0.196 mmol) was added. After about 4 h, the reaction mixture was diluted with EtOAc, filtered, concentrated under reduced pressure, and purified by silica gel chromatography eluting with a gradient of 50-95% EtOAc in heptane to provide 1-cyclohexyl-6-tosyl-6H-imidazo[1,5-a]pyrrolo[2,3-e]pyrazine as a yellow oil (0.020 g, 25%): LC/MS (Table 2, Method a) Rt=2.77 min; MS m/z: 395 (M+H)+.
