A series of 1-alkyl-4-aryl-3,4-dihydro-2(1H)-quinazolinones and thiones were prepared by a modification of the Pictet-Spengler reaction that involves treatment of an N-alkyl-N-arylurea or thiourea with an aryl aldehyde in the presence of methanesulfonic acid. The 1H-nmr spectra of several of these compounds gave rise to unusual OCH2O and isopropyl signals.
