## Abstract The monoamine oxidase inhibitors pargyline and clorgyline have been synthesized by methylation of the appropriate secondary propargylamines, using [^14^C]dimethyl sulphate. This simple method should be generally applicable to other compounds of this class.

Abstract
N‐[3‐(2,4‐dichlorophenoxy)propyl]‐N‐methyl‐2‐propynylamine‐1‐^14^C (^14^C‐clorgyline, 1a) and L‐N, α‐dimethyl‐N‐2‐propynyl‐1‐^14^C‐phenethylamine (^14^C‐L deprenyl, 1b) were synthesized by the Mannich reaction of 2‐methyl‐3‐butyn‐2‐ol, ^14^C‐formaldehyde, and secondary amines 3‐(2,4‐dichlorophenoxy)‐N‐methylpropylamine (2a) or L‐N, α‐dimethylphenethylamine (2b) followed by KOH catalyzed elimination of acetone from the respective Mannich base 3a or 3b.
