実験手順

To a methanol (5 mL) solution of 2-(2-(2-hydroxyethyl)aminoanilin-5-yl)benzoxazole (see Working Example 88-1) (0.10 g, 0.4 mmol) was added methyl acetimidate hydrochloride (0.08 g, 0.7 mmol), and this was heated to reflux for 3 hours. After the reaction was complete, water was added, and the precipitated crystals were filtered, and after being washed with water were dried to yield the title compound (0.05 g, 49% yield) as white crystals.
