Procedure
By the same method as in the step d) of Example 2, 2,2-dimethyl-3,4-dihydro-2H-pyrido[4,3-b][1,4]oxazine (60 mg, 0.36 mmol) was reacted with 3,5-dibromo-4-methoxy-benzoyl chloride (120 mg, 0.36 mmol) to obtain the target compound, (3,5-dibromo-4-methoxy-phenyl)-(2,2-dimethyl-2,3-dihydro-pyrido[4,3-b][1,4]oxazin-4-yl)-methanone (73 mg, 44%).
