실험 절차
Into a 100-mL round-bottom flask containing a solution of ethyl 2-amino-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate (4.06 g, 18.02 mmol, 1.00 equiv) in 100 mL of formamide was stirred for 8 h at 160° C. in an oil bath under nitrogen. The reaction mixture was cooled to 0° C. and diluted with water. The solids were filtered and precipitated with ethyl acetate to provide 8-thia-4,6-diazatricyclo[7.4.0.0[2,7]]trideca-1(9),2(7),3,5-tetraen-3-ol (3.0 g, 81%) as a light yellow solid.
