Condensation of Amines with <i>S</i> -Methyl Thiouronium Salts: Another Entry for the Synthesis of Amidines
- 1. Yildiz Tech Univ, Fac Arts & Sci, Dept Chem, TR-34210 Istanbul, Turkiye
Description
We present a condensation of primary aryl or alkyl amineswith S-methyl thiouronium salts to obtain N,N,N '-trisubstituted amidines. High yields, short reaction times, and a fair substrate scope arethe noteworthy features of this protocol. Surprisingly, the reaction of athiouronium salt with 4-aminopyridine gave 1-(4-methoxybenzo-yl)piperidine.
