Quinazolin-4(3<i>H</i>)-ones and 5,6-Dihydropyrimidin-4(3<i>H</i>)-ones from β-Aminoamides and Orthoesters
Quinazolin-4(3<i>H</i>)-ones have been prepared in one step from 2-aminobenzamides and orthoesters in the presence of acetic acid. Simple 2-aminobenzamides were easily converted to the heterocycles by refluxing in absolute ethanol with 1.5 equivalents of the orthoester and 2 equivalents...
