실험 절차

By the same method as in Example 6, (3,5-dibromo-4-methoxy-phenyl)-(2,2-dimethyl-2,3-dihydro-pyrido[4,3-b][1,4]oxazin-4-yl)-methanone (70 mg, 0.15 mmol) was reacted with 1M solution of boron tribromide (0.9 ml, excess amount) to obtain the target compound 9, (3,5-dibromo-4-hydroxy-phenyl)-(2,2-dimethyl-2,3-dihydro-pyrido[4,3-b][1,4]oxazin-4-yl)-methanone (33 mg, 49%).
