Reaktionsschritte

To a suspension of 2-(4-fluoro-3-nitrophenyl)benzoxazole (see Working Example 15-2) (250 mg, 0.968 mmol) in acetonitrile (5 mL) was added triethylamine (245 mg, 2.42 mmol) and 4-carbomethoxybenzylamine hydrochloride (215 mg, 1.07 mmol), and this was heated to reflux for 2 hours. After the reaction was complete, this was cooled to room temperature, water was added, and after the precipitated crystals were filtered and washed with water, they were dried to yield the title compound (372 mg, 95% yield).
