실험 절차
A 20 ml pyridine solution of 10 g of 6-chloronicotinic acid and 27 ml of 40% methylamine aqueous solution was heated at 150° C. for 24 hours in a sealed tube. After spontaneous cooling to room temperature, this was mixed with water and adjusted to pH 3 with 1 N aqueous hydrochloric acid. The precipitated crystals were collected by filtration to obtain 5.82 g of the title compound as grayish white crystals.
