Reaction Steps
To a solution of 2,4-dichloro-5-nitropyrimidine (1.03 g, 5.15 mmol) in THF (40 mL) at −78° C., DIPEA (2.0 mL, 11.86 mmol) and tetrahydro-2H-pyran-4-amine (0.54 mL, 5.15 mmol) were added. The reaction mixture was stirred from −78 to −50° C. for 5 h. The crude mixture was quenched with H2O (50 mL), extracted with EtOAc (3×40 mL) and the combined organic phases were dried over anhydrous Na2SO4, filtered and concentrated. The crude product thus obtained was chromatographed over silica gel using EtOAc/hexanes mixtures of increasing polarity as eluent, to afford 1.04 g of the desired compound (78% yield).
