Reaction Steps

To a solution of 5-(benzoxazol-2-yl)-2-(tetrahydropyran-4-yl)aminoaniline (see Working Example 20-2) (150 mg, 0.485 mmol) in dimethylformamide (3 mL) was added p-anisaldehyde (79.2 mg, 0.582 mmol) and oxone (179 mg, 0.291 mmol), and this was stirred at room temperature for 2 hours. After the reaction was complete, aqueous potassium carbonate solution was added, and after this was filtered and washed with water, drying yielded the title compound (184 mg, 89% yield) as pale yellow crystals.
