Alkylation of 1H-azoles by salicyl alcohol to give 2-(1H-azolylmethyl)phenols has been studied in some detail [1-3]. In the presence of good leaving groups in the azole molecules a subsequent cyclization of the initially formed alkylation products can occur to give azolo[1,3]benzoxazines [4]. We propose a simple, one-stage method for the preparation of the 1,2,4-triazolo[5,1-b][1,3]benzoxazines 2a,b through the reaction of 3-chloro-1,2,4-triazole (1a) or 3,5-dibromo-1,2,4-triazole (1b) with salicyl alcohol in refluxing DMF in the presence of K2CO3. The reaction occurs through the stage of intermediate formation of o-methylenequinone generated in situ from salicyl alcohol. IR spectra were recorded on a Shimadzu FTIR-8400S spectrophotometer for KBr tablets. The H NMR spectra were taken on a Bruker AM-400 (400 MHz) spectrometer using DMSO-d6 and with TMS as internal standard. Mass spectra were recorded on a Finnigan Trace DSQ chromato-mass spectrometer with direct introduction of the sample into the ion source.
