Downstream synthetic route of 875444-08-9

As the paragraph descriping shows that 875444-08-9 is playing an increasingly important role.

875444-08-9,875444-08-9, (4S,5R)-5-(3,5-Bis(trifluoromethyl)phenyl)-4-methyloxazolidin-2-one is a oxazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

A solution of (45,5J?)-5-[3;5-bis(trifluoromethyl)phenyl]-4-methyl-1,3-oxazolidin-2-one (12.00 g, 38.3 mmol) in THF (200 mL) was cooled to 0 C. NaH (0.919 g, 38.3 mmol) was added. The mixture was stirred at 0 C for 30 min. The title compound from Step A (10.0 g, 31.9 mmol) in THF (30 mL) was added. The mixture was stirred at 0 C and then room temperature for 4 h. Saturated NH C1 (10 mL) was added. The mixture was extracted with ethyl acetate (3 xlOO mL). The combined organic fractions were washed with brine (saturated, 20 mL), dried (Na2S0 ), filtered and the solvent was evaporated under reduced pressure. The residue was purified by column chromatography on silica gel Biotage 65i, eluting with EtOAc/hexane (20/80) to give the title compound as a colorless solid. NMR (CDCl3s 500 MHz) delta 8.57 (s, 1H), 7.94 (s, 1H), 7.82 (s, 2H), 5.86 (d, J= 8.5 Hz, 1H), 4.97 (d, J- 18.0 Hz, 1H), 4.46 (m5 1H), 4.28 (d, J= 17.5 Hz, 1H), 2.60 (s, 3H), 0.83 (d, J= 6.5 Hz 3H)
