Abstract

(ring‐4,6‐^14^C) Pentamethylmelamine (^14^C‐PMM), a new antitumor agent, was prepared from barium (^14^C) carbonate by a 6 step synthesis. (^14^CN) Dimethylcyanamide, prepared from sodium (^14^C) cyanide with 71% yield and treated with phosgene in the presence of hydrogen chloride, was cyclized to (ring‐4,6‐^14^C)‐2‐chloro‐4,6‐bis (dimethylamino)‐s‐triazine. The latter was purified by silicagel low pressure liquid chromatography (15% yield based on nitrile) and condensed with monomethylamine to give ^14^C‐PMM. After purification ^14^C‐PMM was obtained with 91% yield, specific activity = 38 mCi/mMole. The mechanism of the reaction of nitrile with phosgene was discussed.

## Abstract Benzoyl chloride‐7^14^C is condensed with tris(trimethylsilyl) 1‐lithio‐1,1,2 propane tricarboxylate, which after hydrolysis gives rise to a 66% yield of 2‐methyl‐3‐(benzoyl‐7‐^14^C) propionic acid. After cyclisation with hydrazine, followed by treatment with bromine in acetic acid, 3‐h
