Reaction Steps
To a solution of 4-(4-aminophenyl)-N-(4-morpholinophenyl)pyrimidin-2-amine 249(a) (521 mg, 1.5 mmol), N-CBZ-D-Serine (359 mg, 1.5 mmol), and DIEA (0.653 mL, 3.75 mol) in DMA (4 mL) was added HATU (855 mg, 2.25 mmol) and the solution was stirred at room temperature for 0.5 hour. Excess H2O was added to the reaction mixture. The precipitate was collected and were redissolved in CH2Cl2, washed with NaHCO3 (aq) (2×), brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by silica column chromatography. (1% MeOH/DCM as eluent) to afford (R)-benzyl 3-hydroxy-1-(4-(2-(4-morpholino-phenylamino)pyrimidin-4-yl)phenylamino)-1-oxopropan-2-ylcarbamate 365(a) (668 mg, 78% yield).
