Reaction Steps

2-(4-chloro-6-[(1S)-2,3-dihydro-1H-inden-1-ylamino]pyrimidin-5-yl}ethanol (2.80 g, 9.66 mmol), phthalimide (1.56 g, 10.6 mmol) and triphenylphosphine (2.79 g, 10.6 mmol) were dissolved in THF (105 mL) and the solution was cooled at 0° C. DIAD (2.09 mL, 10.6 mmol) was added dropwise and the mixture was stirred 23° C. for 1 hour. The solvent was removed in vacuo and the residue was purified using chromatography on silica gel using gradient 10 to 50% ethyl acetate in hexane to afford the title compound (3.50 g, 86%). LC/MS: Rt=2.12 min, ES+ 419 (AA standard).
