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, 0.040 mmol) from Example 137, Step 3 was stirred in ethanol (0.58 mL), followed by addition of sodium tetrahydroborate (2.3 mg, 0.060 mmol). The mixture was stirred at room temperature for 1 h. Purification by preparative LCMS (pH 10) afforded the title compound. LCMS calc. for C20H19N4O4 (M+H)+: m/z=379.1. found: 379.2.
