Versuchsvorschrift

A solution of 2-{4-[4-cyclopropyl-5-(cyclopropyl-methyl-amino)-8,8-dimethyl-5,6,7,8-tetrahydro-naphthalen-2-ylethynyl]-phenyl}-propionic acid methyl ester (Intermediate 165, 0.075 g, 0.16 mmol) in methanol (2 mL) and tetrahydrofuran (2 mL) was treated with 2M lithium hydroxide (1 mL, 2 mmol) and the resulting reaction mixture was stirred at ambient temperature for 5 h. 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 a yellow solid (0.07 g, 96%).
