To a solution of n-butanol (0.633 g, 8.54 mmol) in anhydrous DMF (50 mL) at 0° C. under the N2, NaH (0.307 g, 12.8 mmol) was added quickly. The obtained suspension was stirred for 0.5 h at 0° C. 2,4-Dichloro-6-(morpholin-4-yl)pyrimidine (2 g, 8.54 mmol) was added to the suspension. After the suspension was warmed to room temperature and stirred for 12 h, the reaction mixture was quenched with ice/brine and extracted with 200 mL EtOAc. The extract was washed with brine, and dried over Na2SO4. The solvent was removed under reduced pressure. The crude residue was purified using flash chromatography (silica; EtOAc/Hexane: 1/6) to yield 1.4 g of 2-n-butoxy-4-chloro-6-(morpholin-4-yl)pyrimidine (white solid, 60%).
