General procedure for the synthesis of 3-aminomethylthiophene from 3-cyanothiophene: Ruthenium(II) complex (1 M) and 2-butanol (5 mL) were added to a 25 mL flask under argon protection and stirred for 5 min at room temperature. Subsequently, KOtBu (0.05 mM) was added and stirring was continued for 5 minutes. Next, 3-cyanothiophene (0.5 mM) was added and the reaction mixture was heated on a hot plate at 120°C for 30 minutes. Upon completion of the reaction, the catalyst was removed by addition of petroleum ether followed by filtration. The filtrate was neutralized with 1 M HCl. The ether layer was purified by short path silica gel column chromatography. Hexadecane was added to the purified filtrate as an internal standard and the yield of the product 3-aminomethylthiophene was determined by gas chromatography (GC).
