Racemic methyl-3-[[2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]-5-fluoro-pyrimidin-4-yl]amino]-2-hydroxy-1-methyl-cyclohexanecarboxylate, 66f, (0.100 g, 0.170 mmol) was dissolved in MeOH (1 mL) and THF (1 mL) and treated with aqueous LiOH (0.24 mL of 1 M solution, 0.24 mmol) and the reaction was heated to reflux overnight. The reaction was cooled to room temperature and the resulting material directly purified by preparatory HPLC to afford 20 mg of racemic 3-[[2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoro-pyrimidin-4-yl]amino]-2-hydroxy-1-methyl-cyclohexanecarboxylic acid. The enantiomers of the racemic material were separated by chiral SFC purification to afford 6 mg of (1R,2R,3R)-3-[[2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoro-pyrimidin-4-yl]amino]-2-hydroxy-1-methyl-cyclohexanecarboxylic acid and 6 mg of (1S,2S,3S)-3-[[2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoro-pyrimidin-4-yl]amino]-2-hydroxy-1-methyl-cyclohexanecarboxylic acid. LCMS: 420.36 (M+1).
