The reaction is carried out in a solvent such as methanol, ethanol, 1,1-dimethylethanol or dimethylformamide at a temperature between 20 0 C and 80 0 C, in the presence of a base such as sodium hydride, or sodium methylate or potassium 1,1-dimethylethylate and optionally in the presence of a catalyst such as lithium, magnesium or zinc bromide or iodide.
In a second step, a B-ketoester of the general formula (IV) is condensed with an amidine of the general formula to give a pyrimidinone of the general formula wherein R and R 5 are as defined above. The reaction is carried out by heating, between 40 0 C and 120 0 C, a mixture of the two compounds, optionally in a solvent such as methanol, ethanol, butanol or toluene, and optionally in the presence of a base such as sodium methylate, potassium carbonate, sodium acetate, pyridine, triethylamine or 4-dimethylaminopyridine.
In a third step, the deprotection and/or the transformation of the group R 5 into the group R 3 is performed, depending on the nature of the group: when R 5 is a carboxylic ester, the compounds of general formula (VI) are converted, by an acidic or a basic hydrolysis, to the compounds of general formula wherein R 1 and R 2 are as defined above and R 3 is a CO 2 H group; the CO 2

Tissues are homogenized in 10 ml of ice-cold 10 mM tris(hydroxymethyl)aminomethane buffer solution, containing 0.33 M sucrose and 1 mM ethylenediaminetetraacetic acid, adjusted to pH 7.4 with hydrochloric acid, in an electrical Potter apparatus at a speed of 1200 revolutions per minute.
The volume of the preparation is adjusted to 25 ml with trissucrose buffer, before centrifuging for 15 min at 1075 g. The supernatant is kept, the pellet is rehomogenized in 10 ml of tris-sucrose buffer and centrifuged as described above. Both supernatants are pooled and centrifuged for 30 min at 47 800 g. The resulting pellet is resuspended in 150 volumes 100 mg of tissue in 15 ml of buffer) of an incubation buffer containing 50 mM tris-HCl, 150 mM NaCI, 5 mM ethylenediaminetetraacetic acid, 1.25 pg/ml bacitracin, 100 uM phenylmethylsulfonylfluoride and 0.2 bovine serum albumin (pH 7.4 at 25 0

The animals are pithed through the orbit of the right eye with a metal rod. The right and left vagus nerves are sectionned (bivagotomy); the right carotid artery is ligatured, the left carotid artery being catheterized in order to measure the blood pressure using a pressure cell (Statham T P23Db type). A femoral vein is catheterized for i.v. administration of drug.
