A mild, efficient and novel synthesis of 2,3-dihydro-1-hydroxyquinazolin-4(1H)-ones via cyclization of 2-nitrobenzamides and ketones induced by tin(II) chloride dihydrate is described. This new method has the advantages of accessible starting materials, convenient manipulation, short reaction times, and high yields.
