es may be prepared by acylation of an N-unsubstituted aniline with 2-chloroethyl chloroformate, ring closure to oxazolidinone, ring opening with alkoxide under anhydrous conditions to a carbamic acid salt, and decarboxylation. This unexpected mode of ring opening is especially useful in the preparation of N-(2-alkoxyethyl)-2,6-disubstituted anilines.
N-(2-烷氧基乙基)苯胺可通过以下方法制备:将N-未取代的苯胺与2-氯乙基氯甲酸酯酰化,闭环成恶唑烷酮,在无水条件下用醇盐开环成氨基甲酸酯,并脱羧。这种意想不到的开环方式在制备N-(2-烷氧基乙基)-2,6-二取代苯胺中特别有用。
