Phosphoric Acid → HCID 71727008, compound

Participants

Reaction Steps

Phosphoric acid (0.40 g, 3.98 mmol), 4 Å molecular sieves (5 g) and N-iodosuccinimide (0.46 g, 1.99 mmol) were added to (S)-1-(1-(4-chloro-3-fluorophenyl)-2-((methylthio)methoxy)ethyl)-4-(2-((tetrahydro-2H-pyran-4-yl)amino)pyrimidin-4-yl)pyridin-2(1H)-one (0.50 g, 1.00 mmol) in DMF (5 mL). The mixture was stirred at room temperature for 2 hours. The mixture was quenched with sodium thiosulfate. Sodium carbonate was added to bring pH to 10, and the solvent was removed. The resultant was purified by HPLC to afford (S)-(2-(4-chloro-3-fluorophenyl)-2-(2-oxo-4-(2-((tetrahydro-2H-pyran-4-yl)amino)pyrimidin-4-yl)pyridin-1(2H)-yl)ethoxy)methyl dihydrogen phosphate (13 mg). M+1=555.1.
