Versuchsvorschrift

6-(1-tert-butyl-1H-pyrazol-4-yl)-3-(difluoromethyl)-3H-imidazo[4,5-c]pyridin-4(5H)-one 2.33 (33 mg, 0.107 mmol), lactam alcohol 1.05 (42 mg, 0.16 mmol), and PPh3 (44 mg, 0.17 mmol) were taken up in THF (1 mL). To the resulting suspension was added DEAD (26 μL, 0.17 mmol) dropwise. The resulting cloudy solution was heated to 40° C. and stirred 1.25 h. The solution was then diluted with DCM and concentrated directly onto silica gel. Purification by silica gel chromatography (15% to 60% acetone in hexanes) afforded (R)-4-((R)-1-(6-(1-tert-butyl-1H-pyrazol-4-yl)-3-(difluoromethyl)-3H-imidazo[4,5-c]pyridin-4-yloxy)ethyl)-1-((R)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one 2.34 that was used without further purification.
