4-bromo-3-[(dimethylamino)methyl]aniline

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: At 0° C., LAH (1.5 g 40 mmol) was added slowly in several portions into a suspension of 5-amino-2-bromo-N,N-dimethylbenzamide (compound 26) (3.1 g, 12.7 mmol) in THF. The reaction mixture was stirred at 0° C. for 2 hours. Then at 0° C. water was added dropwise to the reaction solution slowly until there was no bubble forming in the reaction. After ethyl acetate was added, the reaction mixture was stirred for 30 minutes. The mixture was filtered, washed three times with ethyl acetate. The solvent was evaporated to give a crude product, which can be directly used for the next step. forming in the reaction the reaction mixture was stirred for 30 minutes The mixture was filtered washed three times with ethyl acetate The solvent was evaporated
