## Abstract A convenient synthesis of [1‐^14^C]acetylcholine iodide in two steps is described. β‐Dimethylaminoethanol is acetylated with [1‐^14^C]acetic anhydride and the ester β‐dimethylaminoethyl [1‐^14^C]acetate quaternised with methyl iodide to afford [1‐^14^C]acetylcholine iodide in an overall
## Abstract p‐Toluic acid‐ring‐^14^C was synthesized by the Friedel‐Crafts p‐carbamylation of toluene‐ring‐^14^C with N,N‐disubstituted carbamyl chloride and subsequent hydrolysis. The radiochemical yield was 61%. An attempt was made to apply this method for the synthesis of benzoic acid‐ring‐^14^C
## Abstract 1,1,1‐Trifluoro‐2,3‐alkanediones **2** easily obtainable from various aldehyde dialkylhydrazones were reacted with several diamines to afford trifluoromethylquinoxalines **3** and trifluoromethylpyrazines **4** in good yields. With the use of aldehydes and aqueous ammonia instead of dia
