HCID 219488503-[1-(5-Fluoro-2-hydroxyphenyl)cycloprop-1-yl]-1-(2-(hydroxymethyl)quinolin-5-ylamino)-2-(trifluoromethyl)propan-2-ol

Procedure

Analogously to Example 38, 100 mg (0.22 mmol) of 3-[1-(5-fluoro-2-methoxyphenyl)cycloprop-1-yl]-1-(2-(hydroxymethyl)quinolin-5-ylamino)-2-(trifluoromethyl)propan-2-ol is reacted with 4.40 ml (4.40 mmol) of a 1 M boron tribromide solution. After working-up and purification on silica gel with hexane-ethyl acetate (0–100%) as well as with ethyl acetate-methanol (0–20%), 50 mg (50% of theory) of the product is obtained.
