Procedure

Two grams of 3-methoxy-2-(2-pyridyl)propionitrile is dissolved in 1.5 g. of triethylamine and 2 g. of dry pyridine, saturated with hydrogen sulfide. The mixture is heated at 100° C. in a sealed bomb for 15 hours. The mixture is cooled, diluted with water and extracted with ether. The organic phase is dried, the solvent is removed and the residue is recrystallized from benzene-petroleum ether to give 3-methoxy-2-(2-pyridyl)thiopropanamide.
