Morpholine → N-(2-methoxy-6-nitrophenyl)-2-morpholin-4-ylacetamide

関与物質

反応手順

To a solution of 2-bromo-N-(2-methoxy-6-nitrophenyl)acetamide (Step 1, 8.8 g, 30 mmol) in THF (240 mL) was added morpholin (11 mL, 122 mmol) at 0° C. and warmed to rt. After 2.5 h, the reaction mixture was quenched by addition of water (200 mL) and extracted with ethyl acetate (200 mL×2). The combined organic layers were washed with water (200 mL), brine (100 mL) dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with hexane/ethyl acetate (2/1) to afford 6.7 g (75%) of the title compound.
