Participants

Reaction Steps

Analogously to example 10 40 mg (0.08 mmol) 2,4-difluoro-α-[(ethylsulfanyl)methyl]-3-methoxy-β-[(2-methylquinolin-5-yl)amino]-α-(trifluoromethyl)benzeneethanol in 1.6 ml dichloromethane are treated with 0.8 ml of a 1 M solution of boron tribromide in dichloromethane at −20° C. The typical work up after 22 hours at room temperature and chromatography on silica gel (acetone in hexane 50%) yields 26 mg of the desired product.
