Reaction Steps
A mixture of N-[2-[(2-amino-2-oxoethyl)amino]-3-pyridinyl]-4-chlorobenzamide (6.0 g, 0.02 mole) in 150 ml of ethylene glycol was heated at 190° C. for 40 minutes. The precipitate, which formed, was filtered off and washed with water. The filtrate was diluted with water to produce a second crop. The first crop was heated to boiling in 300 ml of methanol, filtered through a Celite pad, seeded, and refrigerated overnight. The crystalline precipitate was filtered, washed with cold methanol, and dried under high vacuum at 60° C. overnight to give 1.42 g (25%) of title compound, mp 270°-1° C.
