Reaction Steps

A solution of 1.0 g. (0.005 mole) of 3-methyl-2-(2-pyridyl)thiobutanamide in 20 ml. of methanol is treated with 0.65 g. (0.0075 mole) of piperidine and then with 0.23 g. of formaldehyde. The mixture is kept for 72 hours at 25°C., then concentrated in vacuo at 25°C. The residue is suspended in water and then extracted into chloroform. The chloroform is evaporated from the extracts and the residue is dissolved in hexane and cooled to -60°C. on a dry ice bath. Upon warming to 25°C., the hexane solution was decanted from insoluble oil and then evaporated in vacuo. The residue is vacuum dried at 0.005 mm. and 25°C. to give 3-methyl-N-piperidinomethyl-2-(2-pyridyl)thiobutanamide.
