Reaction Steps

To a stirred solution of N-(6-fluoro-6,7,8,9-tetrahydro-5-H-benzocyclohepten-5-yl)-O-methyl-hydroxylamine (0.100 g; 0.48 mmol), prepared as described in example P2b and triethylamine (0.073 ml; 0.53 mmol) in dichloromethane (1 ml) under nitrogen at 0° C. was added drop wise 3-difluoromethyl-1-methyl-1H-pyrazole-4-carbonyl chloride (0.093 g; 0.48 mmol). The reaction mixture was stirred at 20° C. for 15 h under nitrogen. The solvent was removed in vacuo to afford a sticky oil which was subject to flash chromatography (eluant: c-hexane/ethyl acetate 95:5 to 0:100) to afford 0.134 g (76% of theory) of 3-difluoromethyl-1-methyl-1H-pyrazole-4-carboxylic acid (6-fluoro-6,7,8,9-tetrahydro-5-H-benzocyclohepten-5-yl)-methoxy-amide as an oil.
