HCID 157124944-[(2-Fluorophenyl)amino]-5,6-dihydro-2(1H)-pyridinoneYield 82.2%

Procedure

A mixture of 2-fluoroaniline (0.98 g) and 2,4-dioxopiperidine (1.0 g) was heated at 120° for 2 h. The cooled mixture was triturated with dry ether (5×40 ml) and the solvent was decanted to leave the title compound (1.495 g), m.p. 98°-100°.
