YieldReaction ConditionsOperation in experiment
With hydrogenchloride; potassium tert-butylate; In water; toluene; EXAMPLE 4 Preparation of 2-(5-isopropyl-5-methyl-4-oxoimidazolin-2-yl)-5-ethyl-3-pyridinecarboxylic acid With stirring, 225 g (2 moles) of potassium tert-butylate are added in portions to a solution of 251 g (1 mole) of diethyl 5-ethyl-2,3-pyridinedicarboxylate and 130 g (1 mole) of <strong>[40963-14-2]2-amino-2,3-dimethylbutyramide</strong> in 1000 ml of dry toluene, whereupon the temperature of the reaction mixture rises to 80 C. When the addition of potassium tert-butylate is complete, the red solution is stirred for 4 hours at 80 C., whereupon the potassium salt of 2-(5-isopropyl-5-methyl-4-oxoimidazolin-2-yl)-5-ethyl-3-pyridinecarboxylic acid precipitates in the form of a dense crystal slurry. The mixture is cooled to room temperatur and, after addition of 1000 ml of water, stirred until the potassium salt is completely dissolved. The organic phase is then separated and the aqueous phase is adjusted to pH 3 by addition of 165 ml of 37% hydrochloric acid. The mixture is subsequently stirred for 1 hour at 0 C. and then filtered, affording 214.4 g (74.2% of theory) of 2-(5-isopropyl-5-methyl-4-oxoimidazolin-2-yl)-5-ethyl-3-pyridinecarboxylic acid of m.p. 171-173 C.
