Reaction Steps

A solution of the methanesulfonic acid 5-(4-[5-(acetylamino-methyl)-2-oxo-oxazolidin-3-yl]-2-fluoro-phenyl}-pyridin-2-ylmethyl ester 106 (220 mg, 0.5 mmol) in DMF (4.0 mL) was treated with C-isoxazol-4-yl-methylamine (68 mg, 0.5 mmol, 1.0 equiv) at room temperature, and the resulting reaction mixture was warmed to 60° C. and stirred for 6 hours. When TLC and MS showed the reaction to be complete, the reaction mixture was concentrated in vacuo, and the residue was directly purified by column chromatography (0-5% MeOH/CH2Cl2 gradient elution) to afford the desired N-{3-[3-Fluoro-4-(6-{[(isoxazol-4-ylmethyl)-amino]-methyl}-pyridin-3-yl)-phenyl]-2-oxo-oxazolidin-5-ylmethyl}-acetamide 4252 (22 mg, 10%) as off-white solids. LCMS (El): 440 (M++H).
