Versuchsvorschrift
By the same method as in the step c) of Example 2, 2,2-dimethyl-4H-pyrido[4,3-b][1,4]oxazin-3-one (120 mg, 0.67 mmol) was reacted with 1.0M Lithium aluminum hydride dissolved in tetrahydrofuran (1.4 ml, 1.4 mmol) to obtain 2,2-dimethyl-3,4-dihydro-2H-pyrido[4,3-b][1,4]oxazine (110 mg, quantitative yield).
