The base catalyzed intramolecular nucleophilic cyclization of 1-(2-bromobenzoyl)-3-(2-fluorophenyl)thiourea (1) in the presence of N,N-dimethyl formamide (DMF) afforded the 1-(3-fluorophenyl)-2-thioxo-2,3-dihydroquinazolin-4(1H)-one (2) by an intramolecular nucleophilic substitution SNAr mechanism. The structure was supported by the spectroscopic data and unambiguously confirmed by the single crystal X-ray diffraction data. It crystallizes in the orthorhombic space group P na21 with unit cell dimensions a = 22.430(4), b = 8.1478(16), c = 13.522(3) Å, V = 2471.2(9) Å3. There are two independent molecules per asymmetric unit that are linked to centrosymmetric AB-dimers via intermolecular N-H…S bonds. View Full-Text
