Abstract
-Ethyl-N-methyl-3-[1-(dimethylamino)ethyl]carbamic acid, phenyl-2-H-3- ester, (L)-2,3-dihydroxybutanedioic acid salt was synthesized via dire cted ortho-metallation methodology. ethyl-3-[1-(di-(H-2(3))-methylamin o)ethyl]carbamic acid, phenyl ester, (L)-2,3-dihydroxybutanedioic acid salt was synthesized from 3-hydroxyacetophenone. The molecule was res olved by classical diastereomeric salt formation and fractional crysta llization The carbon-14 analog, -methyl-3-[1-(dimethylamino)ethyl-1-(C -14)carbamic acid, phenyl ester, (L)-2,3-dihydroxybutanedioic acid sal t was constructed starting from 3-iodoamisole and featured the enantio selective reduction of a methoxylamine intermediate.
