PROCEDURE
实验过程
Liquid ammonia (150 mL) was added to a mixture of 4,7-difluoro-1-((3aS,4R,6S,6aR)-2,2,6-trimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl)-1H-imidazo[4,5-c]pyridine (6-3) (180 mg, 0.6 mmol, 1 equiv) and 4,7-difluoro-3-((3aS,4R,6S,6aR)-2,2,6-trimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl)-3H-imidazo[4,5-c]pyridine (6-4) (180 mg, 0.6 mmol, 1 equiv). The resulting solution was heated in a high pressure vessel to 100° C. for 2 days. The mixture was then concentrated and purified by flash chromatography (12 g SiO2; 20-100% EtOAc in hexanes and then 100% ethanol to elute 6-3) to yield 7-fluoro-1-((3aS,4R,6S,6aR)-2,2,6-trimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl)-1H-imidazo[4,5-c]pyridin-4-amine (6-5) as a tan solid and 7-fluoro-3-((3aS,4R,6S,6aR)-2,2,6-trimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl)-3H-imidazo[4,5-c]pyridin-4-amine (6-6) as a tan solid. LRMS m/z (M+H) 306.9 found, 307.1 required.
