Versuchsvorschrift

The t-butyl N-[4-[(4-chlorophenyl)sulfonyl]-4-(2,5-difluorophenyl)-3-methylbutyl]-N-methylsulfonylcarbamate (136 mg, 0.246 mmol) obtained in Example 243 was dissolved in dichloromethane (4 ml), followed by the addition of trifluoroacetic acid (1 ml) at room temperature. After stirring at room temperature for 6 hours, the reaction mixture was diluted with dichloromethane, washed successively with water, a saturated aqueous solution of sodium bicarbonate, and brine, dried over magnesium sulfate and then, concentrated. The solid thus obtained was recrystallized from ethyl acetate-hexane, whereby the title compound (99.5 mg, 0.220 mmol, 89%) was obtained as colorless needle crystals.
