A solution of 4.8 g. of 1-isopropyl-1-(2,3-dihydro-7-benzofuranyl)urea, 3.4 ml of benzaldehyde, 3 drops of methanesulfonic acid and 150 ml. of toluene is stirred and refluxed under a water separator for 18 hours. The cooled solution is washed with 150 ml. of water, dried with anhydrous magnesium sulfate, filtered and concentrated in vacuo to give an oil of 1-isopropyl-3,4,7,8-tetrahydro-4-phenyl-furo[3,2-h]quinazolin-2(1H)-one.
