Dimethylamine → HCID 67505515, compound

Participants

Reaction Steps

To a solution of N-[4-chloro-2-(2-methyl-benzoyl)-phenyl]-benzamide (5.1 g, 14.6 mmol) and N-bromosuccinimide (2.85 g, 16 mmol) in CCl4 (150 mL) was added 2,2′-azobisisobutylnitrile (0.2 g, 1.5 mmol). The solution was refluxed for 4 h. The solution was then cooled to room temperature, diluted with CH2Cl2 (150 mL) and washed with H2O (3×50 mL). The organic portion was dried over Na2SO4 and evaporated to dryness in vacuo to provide N-[2-(2-bromomethyl-benzoyl)-4-chloro-phenyl]-benzamide (4.6 g, 74%). A solution of the benzamide (2.3 g, 5.4 mmol) in CH2Cl2 (50 mL) was saturated with dimethylamine, stirred for 16 h and evaporated to dryness in vacuo. The resulting residue was dissolved in MeOH (50 mL) and KOH (0.9 g, 16 mmol) in H2O (5 mL) was added. The solution was refluxed for 24 h. The solution was concentrated in vacuo and then diluted with EtOAc (150 mL) and H2O (50 mL). The organic portion was washed with H2O (3×50 mL), dried over Na2SO4 and purified by column chromatography (silica gel, 18:80:2 MeOH:CH2Cl2:NHOH) to provide 1q (0.9 g, 53% yield) MS m/z=289 (M+H).
