Procedure
5-(1,3-Dioxolan-2-yl)-2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)nicotinic acid (0.507 g, 0.00152 mol), sodium bicarbonate (0.12 g, 0.00143 mol), water and tetrahydrofuran is heated at reflux temperature for 1 hour. Concentration in vacuo yields a solid which is triturated with ether to give the title compound as an orange solid (0.39 g, 72%), mp 209°-210° C., identified by IR and NMR spectral analyses.
