Procedure

Analogously to Example 38, 80 mg (0.15 mmol) of 4-(5-fluoro-2-methoxyphenyl)-1-(2-(morpholin-4-ylmethyl)quinolin-5-ylamino)-4-methyl-2-(trifluoromethyl)pentan-2-ol is mixed with 3.0 ml (3.0 mmol) of a 1 M boron tribromide solution in dichloromethane. After working-up and purification on silica gel with hexane-ethyl acetate (0–100%) as well as ethyl acetate-methanol (0–20%), 53 mg (68% of theory) of the product is obtained.
