3,5-DIBROMOBENZYL BROMIDE Production

The condensation of morpholine (I) with 3,4-difluoronitrobenzene (II) by means of diisopropylethylamine in refluxing acetonitrile gives 3-fluoro-4-(4-morpholinyl)nitrobenzene (III), which is reduced with ammonium formate over Pd/C in THF/methanol to the corresponding aniline (IV). The reaction of (IV) with benzyloxycarbonyl chloride and NaHCO3 in acetone/water yields the carbamate ester (V), which is cyclized with 2(R),3-epoxypropyl butyrate (VI) by means of butyllithium in THF affording 5(R)-(hydroxymethyl)-3-[3-fluoro-4-(4-morpholinyl)phenyl]oxazolidin-2-one (VII). The reaction of (VII) with methanesulfonyl chloride and triethylamine in dichloromethane gives the mesylate (VIII), which by reaction with NaN3 in hot DMF is converted into the azide (IX). The reduction of (IX) with H2 over Pd/C in ethyl acetate affords the corresponding amine (X), which is finally acetylated with acetic anhydride and pyridine.
