Yield:33844-22-3 71%
Reaction Conditions:
with oxalyl dichloride;N,N-dimethyl-formamide in dichloromethane at 0 - 20; for 2 h;
Steps:
45 4-methoxy-2-nitro-benzamide (45)
To an ice cooled suspension of 4-methoxy-2-nitro-benzoic acid (14.1 g, 71.5 mmol) and some drops of DMF in DCM (150 ml) was added drop wise oxalyl chloride (19.0 g, 150 mmol) and the mixture was stirred for two hours at room temperature. The solvent was evaporated and water was added. The product was filtered of and washed with water and hexane. The product was dried in vacuum. Yield: 10 g, 71%.
