## Abstract Several efficient procedures for the synthesis of deuterium, tritium, and ^14^C–labeled acetaminophen, phenacetin, and p‐acetanisidine are described. p‐Aminophenol was acylated by the appropriate acetic anhydride under mild conditions yielding labeled acetaminophen. With 0‐alkylation us
## Abstract The synthesis of indole‐3‐acetyl‐2‐^14^C‐N‐aspartic acid from carrier‐free indole‐3‐acetic acid‐2‐^14^C (54.5 mCi/mmole) and bis‐t‐butyl‐l‐aspartic acid was accomplished by coupling with dicyclohexylcarbodiimide followed by removal of the ester blocking groups by treatment with 2 N NaOH
## Abstract ^3^H‐ and ^14^C‐Labelled doisynolic acid was prepared from 6,7‐^3^H‐, 2,4,6,7‐^3^H‐ and 4‐^14^C‐labelled oestradiol and oestrone by a regulated alkali fusion. Labelled marrianolic acid was similarly prepared from labelled oestriol. Unstability of regiospecific tritium labels in alkali w
## Abstract ^14^C‐Labeled phencyclidine, piperidinocyclohexane carbonitrile and phenylcyclohexene were synthesized chemically from ^14^Clabeled bromobenzene or cyclohexanone. ^3^H‐Labeled __N__‐ethyl‐1‐phenylcyclohexylamine was prepared by reducing __N__‐acetyl‐1‐phenylcyclohexylamine with ^3^H‐lit
