실험 절차

A mixture of 2-methyl-4H-benzo[d][1,3]oxazin-4-one (101 mg, 0.63 mmol) and 1-(3-aminophenyl)-1,4-dihydro-5H-tetrazol-5-one (111 mg, 0.63 mmol) in AcOH (10 mL) was heated to reflux and stirred overnight. Analysis indicated the formation of product. The mixture was allowed to cool and dry-loaded onto silica gel. The mixture was purified by column chromatography on silica gel using CH2Cl2/MeOH (1:0 to 9:1) as eluent to give the product (32 mg, 16% ca. 94% purity by LC/MS). The product was used directly in the next step.
