Tetrahydrofuran → (2-(5-chloro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoropyrimidin-4-ylamino)-1-methylcyclohexanol

Participants

Reaction Steps

To a solution of (3S)-3-[[2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]-5-fluoro-pyrimidin-4-yl]amino]-1-methyl-cyclohexanol, 29f, (2.85 g, 5.38 mmol) in THF (200 mL) was added 1.5 ml 25% W/W sodium methoxide solution at room temperature. The reaction mixture was immediately injected into LC/MS. LC/MS indicated the reaction was complete. The reaction mixture was diluted with 200 ml EtOAc and the organic phase was washed twice with aqueous saturated NaHCO3 and then twice with brine. The organic phase was dried with MgSO4, filtered and concentrated in vacuo. The product was purified by silica gel chromatography (80 g silica, 5% MeOH/CH2Cl2) to afford 1.7 g of the desired product. The resulting product was dissolved in 70 ml THF, to it was added 1.8 ml 5M HCl/IPA. The resulting suspension was stirred for 1 hour at room temperature. The solvent was removed under reduced pressure to afford 1.7 g of the desired product, 655 as an HCl salt.
