Vorschrift

A mixture of (+/−)-ethyl 4-[4,4,4-trifluoro-1-({6-[4-(trifluoromethyl)-1H-pyrazol-1-yl]pyridin-3-yl}amino)butyl]benzoate (46 mg, 0.095 mmol) in methanol (0.19 ml) and tetrahydrofuran (0.095 ml) was treated with aqueous lithium hydroxide (0.095 ml, 0.19 mmol, 2.0M). The mixture was stirred at ambient temperature for 12 hours. The reaction was concentrated in vacuo, then diluted with water and acidified with aqueous 1.0M hydrochloric acid. The mixture was then concentrated in vacuo a second time, and the crude residue was used directly for further transformations.
