Versuchsvorschrift

A solution of 2-{4-[4-cyclopropyl-5-(cyclopropyl-methyl-amino)-8,8-dimethyl-5,6,7,8-tetrahydro-naphthalen-2-ylethynyl]-phenyl}-2-methyl-propionic acid methyl ester (Intermediate 166, 0.125 g, 0.266 mmol) in methanol (2.5 mL) and tetrahydrofuran (2.5 mL) was treated with 3M potassium hydroxide (1 mL, 3 mmol) and the resulting reaction mixture was stirred at ambient temperature overnight. The reaction mixture was neutralized with ammonium chloride and extracted with ethyl acetate. The organic phase was washed with water and brine, and dried over anhydrous sodium sulfate, filtered and evaporated in vacuo to afford the title product as an amorphous pale yellow solid (0.12 g, 98%).
