Vorschrift

A mixture of N-cyclopropyl-2-hydroxy-4-methoxybenzamide (700 mg, 3.38 mmol), (2S)-oxiran-2-ylmethyl3-nitrobenzenesulfonate (876 mg, 3.38 mmol) and Cs2CO3 (1.31 g, 4.05 mmol) in DMF (12 mL) was stirred at room temperature overnight. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was dried over Na2SO4, filtered and concentrated. The residue was purified by silica gel flash chromatography (0-80% ethyl acetate in petroleum ether) to give the subtitled compound (1.0 g).
