Abstract: Condensation of the selectively tosilated N-(2-aminobenzyl)-4-methylbenzenesulfonamide with 2-hydroxybenzaldehyde gives rise to (E)-N-(2-(2- hydroxybenzylideneamino)benzyl)-4-methylbenzenesulfonamide in the solid state, as the crystal structure determined shows, and which in solution shows equilibrium between the acyclic imine and 2-(3-tosyl-1,2,3,4-tetrahydroquinazolin-2-yl)phenol
Keywords: Imine-tetrahydroquinazoline, tautomerism, Schiff base
