Abstract

A convenient method for the preparation of ethyl chlorocarbonate‐^14^C is described. This has led to a facile synthesis of N‐methyl‐^14^C secondary amines by lithium aluminum hydride reduction of an intermediate ^14^C‐carbamate. The reaction has also been employed in the preparation of N‐methyl‐^2^H~3~‐ and N‐methyl‐^3^ H‐amines by using lithium aluminum hydride‐^2^ H~4~and lithium aluminum hydride‐^3^H.
