Procedure

(1-Chloro-2-methyl-propenyl)-dimethyl-amine (16.1 mL, 116 mmol) is added to 3-amino-2,4-dichloro-benzoic acid (20.0 g, 97.1 mmol) in THF (320 mL). After 4 h at rt the mixture is added dropwise to conc. NH3 (320 mL) and stirred at rt overnight. The reaction mixture is concentrated, cooled and filtered. The filtercake is dried to give the sub-title compound.
