Versuchsvorschrift

A mixture of 2-(2-chlorophenyl)acetic acid (1.0 g, 5.9 mmol), O,N-dimethyl-hydroxylamine (0.631 g, 6.3 mmol), EDCI (1.2 g, 6.3 mmol), HOBT (0.874 g, 6.3 mmol), and NMM (2.6 mL, 23.6 mmol) in anhydrous CH2Cl2 (20 mL) was stirred at room temperature for two hours under nitrogen. The reaction mixture was diluted with a mixture of CH2Cl2 and MeOH (v/v=10:1, 100 mL). The organic layer was washed with aqueous HCl (0.5 mol/L, 30 mL×2), saturated NaHCO3 (30 mL×2) and brine (30 mL), dried over Na2SO4, filtered, and concentrated to give crude 2-(2-chlorophenyl)-N-methoxy-N-methylacetamide (0.7 g, yield: 56.0%).
