실험 절차

A round bottom flask was charged with 5,7-dihydro-6H-dibenzo[a,c]cyclohepten-6-one (1.0 g, 4.81 mmol)(CAS #1139-82-8, prepared as described in Tetrahedron Letters, Vol. 28, No. 23, (1987), pp 2633-2636) and butyl nitrite (0.673 ml, 5.77 mmol) (Aldrich) in Et2O. The solution was cooled to 0° C. and treated drop-wise with a saturated solution of HCl(g)/Et2O. After 5 h at 0° C. the resulting precipitate was filtered, rinsed with cold Et2O and vacuum dried to give the title compound as a colorless solid.
