実験手順

3-(difluoromethyl)-6-(3,4-dimethoxyphenyl)-3H-imidazo[4,5-c]pyridin-4(5H)-one 2.29 (49 mg, 0.153 mmol), lactam alcohol 1.05 (60 mg, 0.23 mmol), and PPh3 (60 mg, 0.23 mmol) were taken up in THF (2 mL). To the resulting suspension was added DEAD (38 μL, 0.24 mmol) dropwise. The resulting clear colorless solution was heated to 40° C. and stirred 15 h. The solution was then diluted with DCM and concentrated directly onto silica gel. Purification by silica gel chromatography gave (R)-4-((R)-1-(3-(difluoromethyl)-6-(3,4-dimethoxyphenyl)-3H-imidazo[4,5-c]pyridin-4-yloxy)ethyl)-1-((R)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one 2.30 that was used without further purification. LCMS-ESI+ (m/z): [M+H]+ calcd for C30H33F2N4O5: 567.2; found 567.4.
