Reaction Steps

2-Amino-3,6-dichloro-N-methoxy-N-methyl-benzamide (2491 mg, 10 mmol) were dissolved in THF (100 ml). At −78° C. under nitrogen 1.6 M methyllithium solution in diethylether (25.0 ml, 40 mmol) were added dropwise and the reaction was allowed to reach room temperature and was stirred over night. The reaction was cooled in an icebath and 2N aqueous hydrogen chloride solution (30 ml) were added and the reaction was stirred for 30 min (r.t.). The reaction was diluted with water and extracted twice with diethyl ether. The combined organic layers were washed with saturated aqueous sodium chloride solution, dried over sodium sulfate, filtered and the solvent was evaporated. The residue was purified by column chromatography (CH2Cl2) to yield the product as an orange oil (565 mg, 28%).
