A synthesis of dibucaine labeled with l"C in the heterocyclic ring is described. starting with isatin and acetic anh~dride-2-~"C as shown in Scheme I. Two deutero analogs, dibucaine-d2 and dibucaine-dg, were also synthesized by the reactions shown in Scheme 11. Dibucaine-dg was synthesized by conden
## Abstract ^2^H and ^3^H labelled Sch 40120 were prepared by Pt catalysed exchange with isotopic water. D7‐Sch 40120 was obtained in two exchanges in 53% yield and ^3^H‐Sch 40120 was prepared by a single exchange at a specific activity of 19.8 Ci/mmole. ^14^C‐Sch 40120 was prepared in 4 steps from
