Participants

Reaction Steps

To a solution of 5-Aminomethyl-3-[4-(4-ethyl-2-hydroxyphenoxy)-3-fluorophenyl]-oxazolidin-2-one (10 mg, 0.028 mmol) in 2 ml of dry dichloromethane, cooled to 0° C., was added acetic anhydride (3 mg, 0.028 mmol) taken in 0.2 ml of dichloromethane. The reaction mixture was warmed to rt and stirred for 5 minutes until reaction was complete on TLC. The reaction mixture was diluted with 3 ml of water and the layers separated. The aqueous layer was extracted with dichloromethane and the combined organic fraction was dried over anhydrous Na2SO4 and concentrated. The crude residue obtained was purified by preparative HPLC (Column: C18 Symmetry (300×19 mm), 7μ, Mobile phase A: 20 mM ammonium acetate, Mobile phase B: Acetonitrile) to get 6 mg, 55.2% of the title compound.
