Reactions of tertiary amines
WebThe N -benzyl group of tertiary amines is cleaved by treatment with α-chloroethyl chloroformate followed by reaction with hydroxide, affording secondary amines in good yields < 89TL7383 >. Phenyl chloroformate has been shown to be more effective than alkyl esters, and compares well with the von Braun reaction < 67JCS (C)2015 >.
