実験手順

To a solution of 2-(tetrahydrofuran-2-yl)methylaminoanilin-5-yl)benzoxazole (see Working Example 95-1) (0.15 g, 0.4 mmol) in methanol (5 mL) was added methyl acetimidate hydrochloride (0.05 mg, 0.4 mmol), and this was heated to reflux for 3 hours. After the reaction solution was cooled, water was added, and the precipitated crystals were filtered, and after being washed with water were dried to yield the title compound (0.17 g, 79% yield) as white crystals.
