Condensation of Amines with S-Methyl Thiouronium Salts: Another Entry for the Synthesis of Amidines

Dedicated to Professor H. Ila on the occasion of her 79th birthday
Abstract
We present a condensation of primary aryl or alkyl amines with S-methyl thiouronium salts to obtain N,N,N′-trisubstituted amidines. High yields, short reaction times, and a fair substrate scope are the noteworthy features of this protocol. Surprisingly, the reaction of a thiouronium salt with 4-aminopyridine gave 1-(4-methoxybenzoyl)piperidine.

- 38 Amidines 2; General Procedure A solution of the appropriate S-methyl thiouronium salt 1 (2 mmol), amine (2 mmol), and K2CO3 (2 mmol) in DMF (2 mL) was stirred at r.t. for 2–3 h until the reaction was complete (TLC). Brine (25 mL) was added to the mixture, and the product was extracted with EtOAc (2 × 25 mL). The combined organic layer was dried (Na2SO4) and concentrated under reduced pressure to give a crude product that was purified by column chromatography [silica gel, EtOAc–hexane (1:9)].
