The resulting yellow suspension was stirred overnight at room temperature. Then the mixture was poured into water (150 mL) and extracted with EtOAc (70 mL*3). The combined organic layer was washed with brine (70 ml), dried over MgSO4 and concentrated. The crude product was purified by column chromatography (petroleum ether: EtOAc = 5:1) to obtain the title compound (2.05 g, yield 73%) as a white solid. 1H NMR (400 MHz, CDCl3) δ 8.47 (d, J = 6.0 Hz, 1H), 8.18 (d, J = 6.0 Hz, 1H), 4.81-4.77 (m, 1H), 4.43-4.34 (m, 2H), 2.64-2.56 (m, 1H), 0.99 (d, J = 7.2 Hz, 3H), 0.88 (d, J = 7.2 Hz, 3H)

40.4% With sodium hydride In N,N-dimethyl-formamide; mineral oil at 0 - 20℃; for 12.0833h; Inert atmosphere; (S)-3-(2-chloropyrimidin-4-yl)-4-isopropyloxazolidin-2-one (8) A solution of (S)-4- isopropyloxazolidin-2-one (a) (5.3 g, 41 mmol) and 2,4-dichloropyrimidine (b) (6.1 g, 41 mmol) in 30 mL DMF was cooled to 0 °C under N2 atmosphere. NaH (2.1 g of 60% suspension, 53 mmol) was slowly added to the solution. After 5 min, cold bath was removed. Reaction mixture was allowed to warm to room temperature and stirred 12 h. The reaction mixture was diluted with water and extracted with EtOAc. Organic layer was washed water, and brine. Combined organic layers were dried over Na2SO4, filtered and concentrated. Silica gel column chromatography provided (S)-3-(2-chloropyrimidin-4-yl)-4-isopropyloxazolidin-2-one (8) as a white solid (4 g, 40.4 %). MS m/z 242.09 [M+H]+.
