HCID 27736646-Chloro-2-fluoro-3-methylbenzamide

実験手順

To 6-chloro-2-fluoro-3-methylbenzoic acid (10 g, 53 mmol) is added CH2Cl2 (60 mL), DMF (0.5 mL) and oxalyl chloride (9.25 mL, 106 mmol). The reaction mixture is allowed to stir until it reaches homogeneity and is then concentrated in vacuo. The residue is poured onto a 50:50 mixture of ice and 36% ammonium hydroxide to yield 6-chloro-2-fluoro-3-methylbenzamide.
