Procedure

A solution of ethyl (S)-3-amino-3-(2-methyl-phenyl)-propionate hydrochloride (42.4 g, 174 mmol) in 2-methyltetrahydrofuran (200 ml) was added to the suspension of 1-(2-fluoro-phenyl)-5-methoxy-1H-pyrazole-3-carbonyl chloride in ca. 200 ml of 2-methyltetrahydrofuran obtained in step 1. Triethylamine (33.5 g, 331 mmol) was added dropwise under ice cooling. After the complete addition of the triethylamine the conversion was complete and water was added. The phases were separated and the organic phase was washed with water and evaporated. The residue was dissolved in 2-methyltetrahydrofuran (500 ml) and washed with 1 M hydrochloric acid. The organic phase was dried and the solvent was removed under reduced pressure to give 70.4 g (99% over two step) of the title compound as a light brown oil.
