Versuchsvorschrift

A solution of 2-{4-[5-(cyclopropyl-methyl-amino)-8,8-dimethyl-5,6,7,8-tetrahydro-naphthalen-2-ylethynyl]-phenyl}-propionic acid methyl ester (Intermediate 169, 0.022 g, 0.05 mmol) in methanol (2 mL) and tetrahydrofuran (2 mL) was treated with a 2M solution of sodium hydroxide (1 mL, 2 mmol) and the resulting reaction mixture was stirred at ambient temperature overnight. The reaction mixture was neutralized with saturated aqueous ammonium chloride solution and extracted with ethyl acetate. The organic phase was washed with water and brine, and dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to a residue that was subjected to preparative reverse phase HPLC using 10% water in acetonitrile as the mobile phase to afford the title product (0.008 g, 40%).
