反应条件: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2-n-Butoxyaniline (99 grams; 0.6 moles) and sodium carbonate (31.6 grams) were charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and reflux condenser. 2-Bromomethyl-4,5-dimethyl-1,3-dioxolane (25 ml) was added and the reaction mixture was heated at a temperature of about 100° C. for a period of about 4 hours. After this time the reaction mixture was filtered and additional sodium carbonate (5.0 grams) was added to the filtrate. The mixture was then vacuum distilled and the fraction boiling at 123° C. and 0.05 mm of Hg pressure was collected to yield the desired product N-(4,5-dimethyl-1,3-dioxolan-2-ylmethyl)-2-n-butoxyaniline. equipped with a mechanical stirrer thermometer and reflux condenser After this time the reaction mixture was filtered additional sodium carbonate (5.0 grams) was added to the filtrate vacuum distilled the fraction boiling at 123° C. and 0.05 mm of Hg pressure was collected

实验步骤: Ethyl 1,6-dihydro-2-methylthio-6-oxo-5-pyrimidinecarboxylate (21.5 g) and 2-butoxyaniline (24 g) are added to pyridine (50 ml), and the mixture is refluxed with stirring for 18 hours. The reaction mixture is concentrated to dryness. The residue is recrystallized from DMF to give ethyl 1,6-dihydro-2-(2-butoxyanilino)-6-oxo-5-pyrimidinecarboxylate (20 g). M.p. 209°-211° C. the mixture is refluxed The reaction mixture is concentrated to dryness The residue is recrystallized from DMF
