Reaction Steps

A solution of (2S,6R,8aR)-2-(3-chloro-5-fluorophenylamino)-6-(7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)hexahydroindolizin-3(5H)-one (19 mg) 127.6 in MeOH (0.5 mL) & H2O (2 mL) was treated with of K2CO3 (5 mg, 0.033 mmol) and heated at 70° C. for 24 hours. The white suspension was cooled and diluted with H2O. The precipitate was collected on a Whatman 0.45 um nylon membrane filter and concentrated in vacuo to afford of (2S,6R,8aR)-6-(7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)-2-(3-chloro-5-fluorophenylamino)hexahydroindolizin-3(5H)-one 127.7 (7 mg) as a white solid that exists as 3:1 mixture of diasteromers. LCMS (ESI) m/z: 415.2 [M+H]+.
