반응 단계
To a solution containing 0.54 g of the product obtained in Example 35 in 6 ml dichloromethane 6 ml of 1 molar boron tribromide-dichloromethane solution was added and stirred for 24 h at 20° C. The solvent was evaporated in vacuo and 2 N hydrochloric acid was added to the residue. The product was filtered and washed with water. Recrystallization from isopropanol-water yielded 0.22 g (46%) of the product desired, m.p. 203°-206° C.
