Procedure

Solid N-[3-[(4-chlorobenzoyl)amino]-2-pyridinyl]glycine ethyl ester, 15.5 g (0.04 mole) was heated in glass at 210°-20° C. in a Wood's metal bath for 8 minutes. The residue was dissolved in methylene chloride, treated with charcoal, and filtered through a Celite pad. The filtrate (red) was treated with Florisil® to give a colorless filtrate. The filtrate was evaporated to give a solid, which was recrystallized from tetrahydrofuran-petroleum ether. The solid was collected, washed with petroleum ether (along with a small amount of tetrahydrofuran), and dried under high vacuum at 50° C. overnight to give 7.0 g (48%) of title compound, mp 123°-24° C.
