実験手順

7-(3,5-Dimethylisoxazol-4-yl)-2-oxo-4-pyridin-2-yl-1,2,4,5-tetrahydroimidazo[1,5,4-de][1,4]benzoxazine-9-carbaldehyde (15 mg, 0.04 mmol) from Example 137, Step 3 was stirred in methanol (1.0 mL) with 2-propanamine (10 μL, 0.12 mmol), followed by addition of sodium cyanoborohydride (7.5 mg, 0.12 mmol). The mixture was heated at 60° C. overnight, then diluted with methanol. Purification by preparative LCMS (pH 10) afforded the title compound. LCMS calc. for C23H26N5O3 (M+H)+: m/z=420.2. found: 420.1.
