5-Chloro-N-((S)-2,3-dihydroxypropyl)thiophene-2-carboxamide → 5-Chloro-N-((2R)-2-hydroxy-3-((4-(3-oxo-4-morpholinyl)phenyl)amino)propyl)-2-thiophenecarboxamide

Participants

Reaction Steps

In this case, 5-chlorothiophene-2-carbonyl chloride (IV) is reacted with (28)-3-aminopropane-1,2-diol hydrochloride (VII) to give 5-chlorothiophene-2-carboxylic acid ((S)-2,3-dihydroxypropyl)-amide (IX). Subsequently, (IX) is converted into 5-chlorothiophene-2-carboxylic acid ((S)-3-bromo-2-hydroxypropyl)amide (X), which is then reacted with 4-(4-aminophenyl)-3-morpholinone (III) to give 5-chlorothiophene-2-carboxylic acid {(R)-2-hydroxy-3-[4-(3-oxomorpholin-4-yl)phenylamino]-propyl}amide (XI). Finally, (XI) is reacted with phosgene or a phosgene equivalent to give 5-chloro-N-({(5S)-2-oxo-3-[4-(3-oxo-4-morpholinyl)phenyl]-1,3-oxazolidin-5-yl}methyl)-2-thiophenecarboxamide (I).
