실험 절차

The title compound was prepared from 2,9-difluoro-5-[(4-methoxyphenyl)sulfonyl]-6-methyl-5,6-dihydrophenanthridine (150 mg, 0.37 mmol), cyclohexene (757 μL, 7.5 mmol), and 1.0 M solution of boron tribromide in dichloromethane (2.24 mL) according to the procedure and in the same manner as described in Example 105, step e. The volatile components were removed in vacuo and the crude residue was purified on a Biotage® 40 Mi column of prepacked silica gel (90 g), eluting with a gradient of 5%-50% methyl tert-butyl ether in hexane, to afford the desired compound (117 mg, 81%) as a white solid, m.p. 194-196° C.;
